Question

Tell whether the equation represents a direct variation. If so identify the constant of variation. y + 3x = 0

Answer 1

Rewrite: y = -3x

Can you now answer the question?

Answer 2

yes

Answer 3

Two variables related in such a way that their values always have a constant ratio directly vary. the ratio here of x/y is -3, which is a constant. since the ratio is constant, the equation represents a direct variation
