Question

Which equation does NOT show direct variation?

a y = ½x
b y + 20 = x + 20
c 12y = x
d y = 34x + 2

Answer 1

Direct variation is

y = kx,

where k is a number.

Solve all the equations for y and see which one does not follow the form y = kx.

Answer 2

i tried and i cant find the answer

Answer 4

i will give medal if you can give me an answer

Answer 5

If it is not a DIRECT variation it has to be something else.

Which equation shows an inverse relationship?

Answer 6

b?

Answer 7

Let's look at the choices, one by one.

A. y = ½x
Here you have y = kx where k = 1/2
The equation in choice A follows the direct variation form, y = kx.
The answer is not A.
Ok?

Answer 8

i said b
