Attending concerts is a favorite form of entertainment for many people. The graph shows concert attendance gradually increased from 1994 to 2004 for concerts at a small town's outdoor concert venue. In 1994, the average attendance was 935, as represented by the point  In 2004, the average attendance was 2350, as represented by the point  We can find an equation of the line segment PQ using a system of equations, and then we can use the equation to approximate the attendance in any of the years between 1994 and 2004.
