y varies directly as x. If x = -4 then y = 10. Find y when x = 2. Write answer as reduced fraction if answer is not integer. y =

The fuel consumption (mpg) of a car varies inversely with its weight. A Ford Focus weighs 3000 pounds and gets 28.7 mpg on the highway. What would the fuel consumption be for a Ford Expedition that weighs 5,500 pounds? Round to the nearest tenth.

Write as the ratio of two integers: (a) 24 (b) 3.57.

Make up an example from your life experience of inverse variation.
