Two hot-air balloons, one red and one blue, took off at the same time from different platforms. Each began
ascending at a constant rate.
The following equation gives the height (in meters) of the red hot-air balloon as a function of time (in
seconds)
h =
-t + 4
The height (in meters) of the blue hot-air balloon as a function of time (in seconds) is given by the following
table of values:
Time (seconds)
Height (meters)
4
5
6
6
8
