1. Match one of these equations to each of the graphs.
a. where d is the distance in miles that you would travel in t hours if you drove at 60 miles per hour.
b. where q is the number of quarters, and d is the number of dimes, in a pile of coins worth $12.50.
c. where A is the area in square centimeters of a circle with radius r centimeters.
Graph 1: d = 60t
Graph 2: q + 10d = 125
Graph 3: A = πr^2
