Question

Which equations represent an indirect variation relationship whit a constant of variation equal to -4? Select ALL correct answers
A) xy = -4

b) y = -4/x

c) y = x/-4

d) y = -4x​

Answer 1

The equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4

Direct and indirect variation

An indirect variation is also known as the inverse variation

If the variable y is indirectly proportional to x , this is expressed as:

y = k/x

where

k is the variation constant

If the variation constant is -4, then;

y = -4/x

Hence the equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
