1. Match each of these equations to one of the graphs.
a. d = 601, where d is the distance in miles that you would travel in 1 hours if you drove at
60 miles per hour.
b. q = 50 -0.4d, where q is the number of quarters, and d is the number of dimes, in a
pile of coins worth $12.50.
C. A = xr?, where A is the area in square centimeters of a circle with radius r centimeters.
2. Label each of the axes with the independent and dependent variables and the quantities
they represent
3. For each function: What is the output when the input is 1? What does this tell you about the
situation? Label the corresponding point on the graph.
4. Find two more input-output pairs. What do they tell you about the situation? Label the
corresponding points on the graph.
