Answer:
c) (8, 20)
Explanation:
We must plug in the given value of x in the function and confirm that the value of y that is returned to us is the correct one.
a) (0, 18)


the values for y do not match, so it is not a solution.
b) (5, 19.5)


again, the values for y do not match so it is not a solution.
c) (8, 20)


For this option, the values of y do match, so (8, 20) are the missing values.
