Solution

Solution Steps

The direct variation equation is given by $ y = kx $, where $ k $ is the constant of proportionality. The question is asking which variable represents the constant of proportionality.

Solution Approach

Identify the variable that represents the constant of proportionality in the equation $ y = kx $.

Step 1: Identify the Equation

The direct variation equation is given by

\[ y = kx \]

where $ k $ is the constant of proportionality.

Step 2: Determine the Constant of Proportionality

In the equation $ y = kx $, the variable that represents the constant of proportionality is $ k $.
