The equation given is –4y = 8x. This equation can be rewritten in the form y = kx, where k is the constant of variation. To do this, let's solve for y:
Divide both sides of the equation by –4 to isolate y:
y = (8x) / (–4)
y = –2x
In this form, the constant of variation k is the coefficient of x. Here, k = –2. Therefore, the constant of variation for the equation –4y = 8x is –2.
For the equation –4y = 8x, what is the constant of variation?
