Answer:

Part A

  • The graph is attached

Part B

For zero number the cost is zero and the rate of change is 25.

  • 0 - 0, 1 - 25, 2 - 50, 3 - 75, 4 - 100

This is the indication of the proportional relationship

Part C

  • It is a constant change as the difference is same for each step - 25
  • The ordered pair (1, 25) shows the unit rate is $25 per pair of shoes

Part D

  • Constant of proportionality is 25

Part E

The equation is:

  • y = 25x,

where y - cost, x - number of pairs of shoes, 25 - constant of proportionality
