Direct Variation: $\frac{y}{x} = k$

$\frac{15}{2} = k$

when y = 7: $\frac{7}{x} = \frac{15}{2}$

14 = 15x

$\frac{14}{15} = x$

Inverse variation: y*x = k

15 * 2 = k

30 = k

when y = 7: 7 * x = 30

$x = \frac{30}{7}$

Maybe solve by dividing. I think 5/6. Sorry math isn’t my strong suit. I’m good at reading.

The answer is 2.

This is because the line crosses the x axis in 2 different places.

Hope this helps!
