Question

What does direct variation look like on a graph?

Answer 1

Depends.

When your direct variation is linear (i.e. `y = kx`), you have a line with a positive slope.

However, there are cases of variation where `y` varies directly as with the square of `x`, your equation would be something like

`y = kx^2`

In this particular case, your graph is half a parabola opening upwards
