Question

This relation is an inverse variation {(-1,8),(4,-2),(-2,4)} what equation represents this relation?

Answer 1

ANSWER

$y = - \frac{8}{x}$

EXPLANATION

An inverse variation equation is of the form:

$y = \frac{k}{x}$

We plug in the point (-1,8).

$8= \frac{k}{ - 1}$

This implies that k=-8

Therefore the inverse variation equation is :

$y = - \frac{8}{x}$
