Question

9. Find the constant of variation, k, for y= –8 when
x = 12.

Answer 1

To find the constant of variation, k, we can use the formula for direct variation:
y = kx

In this case, y = -8 and x = 12.

-8 = k(12)

To find k, divide both sides by 12:
k = -8/12
k = -2/3

Therefore, the constant of variation, k, for y = -8 when x = 12 is -2/3.
