Answer 1

• See below

Explanation:

We see graphs of proportional relationship.

The input value is time in hours and the output is the earning in dollars.

a)

• The green line is steeper than the blue line. It means more earning per hour.

b)

Slopes can be calculated based on one pair of non-zero coordinates.

• Green line: m = 45/3 = 15
• Blue line: m = 40/4 = 10

c)

The difference in slopes gives the difference in earning per hour:

• 15 - 10 = 5
