Question

Which equation represents a constant of proportionality of 25? *

12 points

F. x + 25 = y

G. 25x = y

H. x − 25 = y

J. 5x = y

Answer 1

G

Explanation:

An equation of proportionality has the form

y = kx ← k is the constant of proportionality

y = 25x ← has this form with k = 25

y = 5x ← has this form with k = 5

The required equation is y = 25x with k = 25 → G
