Question

Find the direct variation equation which passes through (0, 0) and (4, 1).
A. y = 4x
B. y = -4x
C. y = 1/4 x
D. y = -1/4 x

Answer 1

I roughly drew that, so that function is increasing or decreasing?

Answer 2

And let's take a look at our slope, since we have a direct variation here, we only have to take rise/run = m

From there, you can get the answer, good luck! :)
