Question

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation

xy = 7

Answer 1

Answer: Choice B

y = 7/x

inverse variation

=========================================================

Step-by-step explanation:

We divide both sides by x to isolate y. That's how we go from xy = 7 to y = 7/x

This is an inverse variation because it's in the form y = k/x. The constant is k = 7.
