Question

Which is the equation of the line on the graph below?

Answer 1

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 :)

Answer 2

the equation to this graph is y = 2x -2
