For the equation -4y = 8x , what is the constant of variation?
a: -4
b: -2
c: 1
d: 2

B: -2

Step-by-step explanation:

Given equation:

To make it in standard form divide both sides by -4, we get

Now this is in the standard form of y = mx, where m is the constant of variation.

Thus, the constant of variation is -2.

The constant of variation (m) is the number that associates two variables that are directly proportional or inversely proportional to each another.
