Answer 2

9514 1404 393

Answer:

5

Explanation:

A proportional relationship has the equation ...

y = kx . . . . . . where k is the constant of proportionality

Solving this equation for k, we get ...

k = y/x

Filling in the given values (x, y) = (4, 20) gives ...

k = 20/4

k = 5

The constant of proportionality is 5.
