Hey there! Direct variation, a concept commonly applied to linear equations.
The constant of variation is a concept which simply refers to the change in y, based on the change in x. If this change is constant, then it is a constant of variation.
You can find the constant of variation (usually referred to as 'k') by dividing any point's y-value by its x-value.
In this instance, we have the point (3.5, 14)
14 / 3.5 = 4
The constant of variation for this equation would be 4.
