Final answer:
The ordered pairs that satisfy the function y = 8r + 20 are (5, 60), (10, 100), (15, 140), and (20, 180).
Step-by-step explanation:
- For the given function y = 8r + 20, substitute the given values for r and calculate the corresponding values for y.
- The ordered pairs that satisfy the function are:
- (5, 60)
- (10, 100)
- (15, 140)
- (20, 180)
