Question

This graph represents a linear function.

Enter an equation in the form y = mx + b that represents the function described by the graph.

Answer 1

y=2x-2

Explanation:

Answer 2

Explanation:

To find the line y=mx+b we need two points. I choose (0,-2) and (1,0)

Since y=mx+b where m=slope and b=y intercept (value of y when x=0)

We have the point (0,-2) so we know b=-2

Now we find the slope which is defined as

m=(y2-y1)/(x2-x1), in this case

m=(0-(-2))/(1-0)

m=2, so the line is

y=2x-2
