Identifying Direct Variation
To determine if an equation shows direct variation, check if it can be expressed in the form y = kx, where k is a non-zero constant. In this case, k = 12.
Finding the Constant
To find the constant of variation:
- Look at the coefficient of x in the equation.
- In y = 12x, the constant is 12.
Thus, the constant of variation in this equation is 12.
