Answer:
Step-by-step explanation:
Two points on this line are (36, 72) and (0, 0). These are 'nice' points in that they are exactly at the intersection of grid lines.
The slope can be found immediately from (36, 72) if the other point is (0, 0):
m = rise / run = 72/36 = 2
Adapting the slope-intercept formula y = mx + b, and using the point (0, 0), we get 0 = 2(0) + b, which tells us that b = 0. Then the equation of the line in this graph is y = 2x.
