If y varies directly with x, find the constant of variation with x = 4 and y = -24A. -6B. 4C. -96D. 6I am a little lost on this. Can someone show me how to do this?

use the formula y=kx for this equation.
so considering that Y equals -24 then X and K must also equal that number
we already know that X is -4 but we dont know what K is.
so we divide -24 by -4 and get an answer of a positive 6 but the answer is not proven yet.
-4 times 6 is -24 meaning that the answer is 6
