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 src="https://sciemce.com/media/4/ppg__rrr0709190917__f1q78g3.jpg" alt="" style="vertical-align: 0.0px;" height="213" width="361" />After forming an equation for the segment, PQ, solve for y, when x = 1996.
A. 2347
B. 51,423.2
C. 218,222
D. 1218
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.
