The point (12,

9) is included in a direct variation. What is the constant of variation?

1 answer

To find the constant of variation, we can use the formula y = kx, where y is the dependent variable, x is the independent variable, and k is the constant of variation.

We are given the point (12, 9), which tells us that when x = 12, y = 9.

Plugging these values into the formula, we get:

9 = 12k

Simplifying, we have:

k = 9/12

k = 3/4

So, the constant of variation is 3/4.
