Answer: (c), (a)
Step-by-step explanation:
Given
1. It is known that the amplitude of the wave is the distance between the maximum or minimum point from the centerline
from the graph, 
is the line about which the distance of the maximum and minimum point is the same i.e.
option (c) is correct
2. For graph second maximum point is 4 and the minimum point is -1, the amplitude is
option (a) is correct
To answer this question you would set this up as an equation with all the information about Al on one side being equal to all the information for Matthew on the other side. This is what it would look like: $25 + $9h= $14h. h represents the number of hours they work. It they each worked 5 hours a week, they would make the same amount of money. I determined this by solving the equation for h. I subtracted 9h on both sides leaving you with $25=5h. H would equal 5 hours.
