which way is the y and x axis.?

Question

like i know the Y is vertical, and the X is horizontal, but when i am graphing a line like y=2x+3

do i graph the Y axis line like its goinq verticle, or horizontal.?
do you get what i mean.??
cuz it always confuses me.

thnkss for helpinqqq. :]

Answer 1

that's is for the equation y=mx+b

so basically 'b' goes along the y axis, (this is the point where your line crosses the y axis) and 'm' is your slope. You figure your slope out by remembering rise over run.

so for your equation you would put a dot on the positive 3 of your y axis. Next you will figure out your slope. 2 is basically 2/1 (so if it was -3 it would be -3/1 and so on. if the equation says 3/4 or something like that you don't need to figure out your slope)

you next place your pencil on the point and move up 2 (rise) and move over one (run) point to the right. and repeat that from each new point . (if your slope is negative, you will go the other way)

next you connect your lines and there is your equation graphed

Answer 2

eg. Y=5



you draw a line through the Y axis where it =5. since the yaxis is verticle, the line cant be verticle and in this case is perfectly horizontal.



eg. y=2x+3



Y axis line is always verticle and x is always horizontal.

Find the point where the line crosses the y axis (x=0)

so.... y=2(0)+3

y=5



then find where the line will pass trhough the x axis (y=0)

so 0=2x+3

-3=2x

-3/2=x

so the line will go from -1.5 on the x axis to 5 on the y axis. Remember Y axis is always Verticle and X is always Horizontal

Answer 3

Ok, the +3 on the end of your equation tells you where the line crosses the y axis.



So, you would go up 3 and put a point there.



Next, the 2x tells you the slope. (imagine a 1 underneath of the 2x. It helps)



So, you go from your original point at 3 on the y axis and go up 2 then right 1. and keep going as long as you want.



That will make your line



Hope that helps :)

Answer 4

YES, with the line y=2x+3, you have to graph the y axis going vertically and the x axix horizontally..

no matter what the equation is, y axis is always vertical and x axis is always horizontal even if the line is horizontal or vertical itself (like if the equation is y=3, Y LINE is horizontal but you still have to draw the Y AXIS LINE vertical) do you get it?





if this isnt what you were looking for, give more details please :)

Answer 5

We had these



what you gotta do is graph a slope, it will be diagonal



the number by it's self is your y-intercept, so when line crosses to y it will cross on the 3(if it was -3 it would cross on -3)



now the 2x is your slope, so you make it a fraction by making it 2/1

now on the graph the bottom is how many you go over and the top is how many squares you go up.

if the slope is possitive like it is here, the line should go from the bottom left to the top right. If the slope was negitive, something like -2

then the line goes from top left to bottom right.

(u know like when a graph show possitive and negitive decline and advance)



So start at your y-intercept, go to the right one unit and up two units, now connect the two points, and continue the lineas far off the graph as u can. make sure to draw arrows at the end of the lines.

Answer 6

try making a chart. make x and y on top of each other than make a horizontal line separating the two and make small boxes by drawing 4-5 vertical lines and plotting number from ex -2 to +2. and than plugging in X into the equation.



ex.

X /-2/-1/0/1/2 Y=2(x)+3

Y/1/?/?/?/? x=-2 than Y=1



and so on. so than you have your coordinates (ex. (-2,1))



got it? message me or something if you have any other questions.

Answer 7

Neither. When you are graphing equations like these: y=ax+b, keep in mind that your b will be your y-intercept. What you do is you have to make a table consisting of some x points to find your y points. I recommend you start with 2, 1, 0, -1, and -2.

Answer 8

Given an x value, calculate the y value. Then, to plot a point, (x, y), start at the origin, (0, 0), then go + x places to the right or - x places to the left. Then from there, go + y places up or - y places down and mark the point with a dot. Do this for each value of x you want to use. Then, just connect the dots.

Answer 9

You can draw a straight line using two points to guide you



When x = 0 then y = 3 ... ((2 times 0) + 3)

When x = 1 then y = 5 ... ((2 times 1) + 3)



Plot those two points and draw a line straight through them

Answer 10

Make a big + sign and label the vertical line (i.e North-South line) "y". The horizontal line is "x". Now plot your line which strikes the y-axis at (0,3) and goes thru any other point that satisfies the equation, such as (1,5).

Answer 11

X is across the bottom (horizontal) and the y-axis is vertical.



Therefore y=2x+3, the gradient is 2x and the intercept on the y axis is +3

Answer 12

Y is vertical. always remember it like youre walking up the morning and stretching and Yawning.



the X is axis goes horizontally. remember it like X-lax that constantly sends you back and forth the to the bathroom.



thats how my 8th grade teacher taught me.

Answer 13

the axis never change for any equation. The Y always goes up and down and the x always go side to side. These lines are like a reference, you need them each time you graph anything.

Answer 14

The X axis is horizontal, the Y axis is vertical.

Answer 15

Y is vertical, like saying to the sky "Y this problem is difficult"



X then must be horizontal

Answer 16

numbering something with a Y is going vertical, but when recording it down it's horizontal

Answer 17

x axis going horizontal and y axis going vertical

Answer 18

the Y-axis is vertical, it goes up and down, and the X-axis is horizontal, it goes left and right.

Answer 19

Picture a guy gesturing with each hand out to the side (the horizontal line), shrugging and saying, why?

And then picture a lady saying "you shall now forever be my EX!" And faving and outsrtetched up finger at her ex boyfriend to be.

**** wait a second I'm wrong.

Gah there goes by best answer. ;)

Answer 20

x is horizontal (like a horizon, side to side)

y is vertical (y rhymes with sky and its going up)

hopefully this helped :)

Answer 21

Here's an example:

Answer 22

y axis is going up x axis is horizontal

Answer 23

the y axis is the one going up and the x axis is the one going across

Answer 24

Y is up and down X is left and right

Answer 25

y is vertical x is horizontal

Answer 26

the y goes up and down the x goes left to right

Answer 27

by convention, x is horizontal and y is vertical.

Answer 28

y axis goes up and down

x axis goes right and left

Answer 29

y axis: | (vertical)







x axis: ----- (horizantel)



hope that helped
