The slope of this graph is 2/1x or 2x, because the line intercepts with a point every time it goes up 2 and right 1 unit. The y-intercept is (0,-2).
We can find the equation using slope intercept form, y=mx+b, when m is the slope and b is the y-intercept. Let's plug the slope and y-intercept into the slope intercept form equation:
y=2x+(-2) or y=2x-2
The answer is B) y=2x-2.
I hope this helps :)
