The point (12,9) is included in a direct variation. What is the constant of variation?
(1 point)
1/2
3/4
1
2
To find the constant of variation, we can use the formula for direct variation, which is y = kx, where k represents the constant of variation.
Using the given point (12, 9), we can substitute the values into the equation to find the value of k:
9 = k * 12
Rearranging the equation to solve for k, we divide both sides by 12:
9/12 = k
Reducing the fraction gives:
3/4 = k
Therefore, the constant of variation is 3/4.
