A group of climbers begin climbing at an elevation of 7000 feet and ascend at a steady rate of
500 vertical feet per hour. This situation can be modeled by a linear function. Identify the
independent and dependent variables. Draw a graph of the function, then use the graph to find
their elevation after 4 hours. Is a linear model reasonable for this situation?
The number of hours is the
