y = kx

//y varies directly with x and k is the constant value.

Find constant k when x = 4 and y = -24.

y = kx

y/x = k

-24/4 = k

k = -6

Answer: -6

Explanation: We know that if y varies directly with x, then we can use the formula y = kx and we're given that x = 4 when y = -24 so we can substitute these values into our formula for x and y to get -24 = k(4).

Now to solve for k, we divide both sides of

the equation by 4 and we have -6 = k.

So -6 is the constant of variation.
