Question

Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.

Answer 1

so whats your variables?

Answer 2

I can give you some for an example and show you?

Answer 3

\[y\propto x\]\[y=kx\]

Answer 4

like -6y = -5x
If y varies directly as x, then y = kx.
-6y = -5x
y = -5x/-6
y = 5x/6
y = (5/6) * x

Answer 5

So, yes, y does vary directly with x, and k = 5/6.

Answer 6

The graph of this equation is a straight line passing through the origin with gradient = k = 5/6.
