Answer:
y = (5/7)x
Explanation:
This line goes through the origin, (0, 0), as well as the arbitrarily chosen point (7, 5). As we go from (0, 0) to (7, 5), x increases by 7 and y increases by 5. Thus, the slope of this line is m = rise / run = 5/7, and the y-intercept is b = 0.
The equation of this line is y = (5/7)x.
