Final answer:
Yes, the equation y=3/4x represents a direct variation where the constant of variation is 3/4.
Step-by-step explanation:
Direct variation is a term used in mathematics to describe a linear relationship between two variables in which one is a constant multiple of the other. In other words, when y varies directly with x, the equation can be expressed as y = kx, where k is the constant of variation.
In the case of the equation y = ¾ x, this is indeed a direct variation because it fits the form y = kx. Here, the constant of variation k is ¾. This means that as x increases or decreases, y will do so at ¾ the rate of x.
