Ok, so here's the graph, let me post my other data

horsegirl27 · Answer

Ok, I'm given this system of equations: y=-x-2 and y=2x-5. I have to find the x-coordinate. But I'm not 100% how to find the x-coordinate. Can someone help explain?

Ok, so look at where the two graphed lines meet. You find the x coordinate by looking at that. http://prntscr.com/6r5qzo When we find a spot on a coordinate plane, we go over and up or down. Going horozontally, which would be like this ----- is on the x axis. and going vertically | is the y axis. How far over do you have to go on the x axis?

whats the question

k_lynn · Answer

Or to solve for x, you can put in 0 for y and solve.

k_lynn · Answer

$$0=(-x)-2$$and$$0=2x-5$$

@girlseed23  the question is to find the x-coordinate. and @k_lynn  i go over 1 on the x axis?

k_lynn · Answer

Right.  So I believe 1 is the x coordinate.

ok

k_lynn · Answer

And if you you don't have a graph, you can always solve for x, by plugging in 0 for the y.

horsegirl27 · Answer

So when I'm finding the x-coordinate, I count how many i go over to get to the y-axis?
