Question

Which equation represents direct variation? A) y = 3x B) yx = 3 C) y = 3x2 D) y = 3x3

Answer 1

Answer:A

Step-by-step explanation:I took the test, and I got this one right

Answer 2

The equation that represents direct variation is
`y=3x`

Explanation:

The general equation of a direct variation is of the form,

`y=mx`.

The constant m is referred to as the constant of proportionality or the constant of variation.

The graph of a direct variation is a straight line that passes through the origin, which has coordinate
`(0,0)`

The equation that represents a direct variation among the options provided is

`y=3x`

Therefore the correct answer is option A.
