The equation that relates x and y is 4 = k/6 and the value of y when x = -8 will be -3.



How to solve the inverse variation?

From the information given, the variables x and y vary inversely, and y = 4 when x = 6. Therefore, the equation that relates x to y will be:

y = k/x

4 = k/6

k = 4 × 6 = 24

The value of y when x = -8 will be:

y = k/6

y = 24/-8

y = -3.
