Question

Match the correct y=mx+b equation to the graph: pls show work/explanation!

Answer 1

Answer:  y = (1/3)x - 2

Explanation:

The y intercept is -2 because the line crosses the y axis at this location. So b = -2

The slope is m = 1/3 because we go up 1 and over to the right 3 units. For instance, going from (0,-2) to (3,-1) follows this pattern.

You can use the slope formula for two points like (x1,y1) = (0,-2) and (x2,y2) = (3,-1) to find that m = 1/3

The slope formula is m = (y2-y1)/(x2-x1)

So that's how we go from y = mx+b to y = (1/3)x-2
