the value of y varies directly with x, and y = -8 when x = 4. what is y when x = -4? y = ? remember: y = kx

Answer:

8

Explanation:

Step1: Find the constant of variation k

Given $y = kx$, when $y=-8$ and $x = 4$. Substitute into the equation: $-8=k\times4$. Solving for $k$, we get $k=\frac{-8}{4}=-2$.

Step2: Find y when x=-4

Use the equation $y = kx$ with $k=-2$ and $x=-4$. Then $y=-2\times(-4)=8$.
