Question

Which equation has a constant of proportionality equal to 5?Choose 1 answerY = 5xY = 10/5xY = 5/25xY = 1-2x

Answer 1

The constant of proportionality is seen as k in this formula:

$\text{ y = kx}$

All of the choices are already in this form, however, the only expression that shows a constant of proportionality of 5 is y = 5x.

$\text{ y = (}k)(x)\text{ }\rightarrow\text{ y = (5)(x)}$

Therefore, the answer is A.
