Hot Air Balloon A hot-air balloon at 1120 feet descends at a rate of 80 feet per minute.
Let y represent the height of the balloon and
let x represent the number of minutes the
balloon descends.
a. Write an equation that relates the height of
the hot air balloon and the number of minutes
it descends.
b. Sketch the graph of the equation.
c. What is the intercept of the graph, and
what does it represent in the context of the problem?
Use the graph or table to write a linear function
that relates y to x.
