Suppose that x and y vary inversely. x = -4/15 when y = -105. Write function that models the inverse variation. Then, find y when x = 10. Write answer as a decimal and round to the nearest tenth, if necessary.

y = __?__ when x = 10.

-105 = k / (-4/15)

so -105 = -15k/4

-4/15 -105

10 x

x/-105 = -15/4/10

x = 2.8
