Answer:

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.
