The point (12,9) is included in a direct variation. What is the constant of variation?
To find the constant of variation in a direct variation, we can use the formula:
y = kx
Where y and x represent the variables, and k represents the constant of variation.
Given that the point (12,9) is included in the direct variation, we can plug in these values to solve for k.
9 = k(12)
Dividing both sides of the equation by 12:
9/12 = k
Simplifying:
3/4 = k
Therefore, the constant of variation is 3/4.
