Answer 1

help

Answer 2

y = 2x is an example of a direct variation equation

Answer 3

since it's in the form y = kx where k is some fixed constant number

Answer 4

so would x=-2y be a direct variation equation too?

Answer 5

yes because you can solve for y to get

x = -2y

-2y = x

y = (-1/2)*x

y = -0.5x
