A 1

B 2

C 4

D 5

Answer 1

Answer:

The correct answer is D, 5

Step-by-step explanation:

If the table represents a proportional relationship between our values x and y, we can find our function.

From our constants in x, the increase is a product of x by 5 to result in y's value. Therefore, the constant unit rate of y per x is 5.
