Question

Y varies directly with x and y= -9 when x= -45

Answer 1

What are you trying to find? The constant?

Answer 2

What is the direct variation equation

Answer 3

I think it is. Y=1/5x

Answer 4

Direct variation equation:

y = kx

Where 'k' is the constant.

Plug in what we know:

-9 = k(-45)

-9 = -45k

Divide -45 to both sides:

-9/-45 = k

1/5 = k

So we have:

y = 1/5x
