Question

Write the inverse variation equation of the following: Y varies inversely with x and y = -12 when x = 6.
xy = -2
xy = -72
xy = -0.5

Answer 1

y = k/x and then plug in the given values.

Answer 2

-72?

Answer 3

-12 = k/6

Now multiply both sides by 6
6(-12) = k

So yes... k = -72

y = -72/x or xy = -72
