Question

The equation y = 5x represents a proportional relationship. What is the constant of proportionality?A. xB. 1/5C. 0D. 5

Answer 1

ANSWER

D. 5

EXPLANATION

We have to find the constant of proportionality in the equation:

$y=5x$

The general form of a proportional relationship is:

$y=kx$

where k = constant of proportionality

Therefore, comparing the given equation with the general equation, the constant of proportionality is 5.
