Answer:
-14
Step-by-step explanation:

The y-intercept of the graph shows that at m = 0, c = 15. We can see a constant slope that causes the graph to pass through m = 20, c = 20, as well as m = 40, c = 25. This shows a constant increase of $5/20 minutes, or a slope of 5/20 = 1/4. Based on slope-intercept form y = mx+b, the equation would be c = (1/4)m+15, from 0 <= m <= 44,640. This is the second of the given choices.
How is anyone supposed to answer this question when you don’t shown the angle
The answer is .002 after you multiply the equations inside the parentheses and divide them
