# If y=-5, when x=9, how do you find y when x=6 given that y varies inversely as x?

Jan 22, 2017

Inverse means that $x \times y = C , C$ being a constant.

#### Explanation:

From the data:

$C = 9 \times \left(- 5\right) = - 45$

Now for $x = 6$:

$6 \times y = - 45 \to y = - \frac{45}{6} = - 7.5$
