Answer:
y = (6/5)x + 3
Explanation:
Two points on this graph are (0, 3) (which is the y-intercept) and (10, 15).
Going from the first to the second, we see that the horizontal distance is 10. This is the 'run.' Simultaneously, the vertical distance is (15 - 3), or 12 ('rise').
Thus, the slope of this line is m = rise / run = 12/10 = 6/5.
Start with the basic slope-intercept formua y = mx + b. Substitute 6/5 for m and 3 for b. We get:
y = (6/5)x + 3, which matches answer choice #1
