In direct variation, the constant of variation (often denoted as k) is the ratio between the two variables.
Given the point (12,9), we can form the equation of direct variation as y = kx.
Substituting the given values, we get 9 = k(12).
Solving for k, we divide both sides of the equation by 12 to isolate k.
k = 9/12 = 3/4.
Therefore, the constant of variation is 3/4.
The point (12,9) is included in a direct variation. What is the constant of variation
