Is $\frac{y}{x} = 8$ $y/x = 8$ a direct variation, inverse variation, joint or neither?

1 Answer

It's a direct variation, as the ratio between $x$ $x$ and $y$ $y$ is constant.

You can rewrite by multiplying both sides by $x$ $x$ :

$y = 8 x$ $y=8x$ which will form a straight line when graphed:
graph{8x [-32.47, 32.47, -16.24, 16.25]}
