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__tttt0623191144__f1q88g3.jpg" alt="" style="vertical-align: 0.0px;" height="213" width="361" />The line segment has an equation that can be written in the form y = ax + b. Use the coordinates of point P with
