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 = \dfrac{1}{2} t + 4h=
2
1

t+4h, equals, start fraction, 1, divided by, 2, end fraction, t, plus, 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) Hight (meters)
4 5
6 6
8 7
