In order to find an equation of a line, you need to find the slope first. Pick two points on the line and use the slope formula to find the slope. As you can see by looking at the line, (0,0) is on the line, and so is (1,2). You only need two points to find the slope, so let's do that!

nvm its d dnt gt to explain lol

Oh ok so the answer is y= 2x
OpenStudy (lolacole12):
yep
OpenStudy (anonymous):
thanks what grade are you n

If the line goes "up" in the postive x direction the slope is positive. If the line goes "down" in the positive x direction the slope is negative. If the line is horizontal the slope is 0. If the line is vertical the slope is undefined
I think it would be A but I'm not sure...anyone else?

I thought A but i wasnt sure

What is the slope of the line passing through the points (–1, 3) and (4, –7)?
A.2
B.3/4
C. -4/3
D.-2
Directrix (directrix):
Look at the graph from left to right.
As x increases, the corresponding values of y are falling.
That means that the line has a negative slope.
For a positive change in x, there is a negative change in y.
