Answer:

C

Step-by-step explanation:

The equation of a line is y=mx+b where m is slope and b is the y-intercept. the y-intercept is where the line crosses the y-axis which is at (0,2) here so b=2.

The slope is found by finding the difference between any two points on the line. To find the difference, choose two points which cross through two grid lines. The only points on this graph which does that is (0,2) and (10,15). Find the slope by subtracting 15-2 / 10-0. This is equal to 13/10 or 13 over 10.

The equation is y = 13/10 x +2.
