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:

y = kx

Given that y = -8 when x = 12, we can plug these values into the formula:

-8 = k(12)

Now we solve for k by dividing both sides by 12:

k = -8/12
k = -2/3

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