Question

suppose y varies directly with X write a direct variation equation that relates X to Y
Y=10.4 when X=4
A.y=3.4x
B.y=3.8x
C.y=3.2x
D.y=2.6x
(I think it's D am I correct?)

anonymous · Answer

is tis the equation to the problem

anonymous · Answer

You are correct, the answer is D.

If you plug in x=4 you find y = 2.6 * 4 = 10.4, which is what we expect.

danjs · Answer

that is the easy way to do it if they give you answer choices all in the form of a direct variation y=k*x

danjs · Answer

It is a line through the origin (0,0)
