1. Extra Review for Graphing Test

2. Graphing
A line passes through the points (-2,9) and (2,7)
Give the equation of the line in all three ways:
Point/Slope Form
Slope/Intercept Form
Standard Form

3. Modeling
The High School Honor Society is taking a trip to NYC to go ice skating in Rockefeller Center. They have two options.
If they take a coach bus, it will cost $1250 for the bus plus $40 per student to ice skate.
If they take the train, it will cost $78 per student for a train ticket and ice skating
Make an equation for each option
Which equation has the steeper slope?
If 55 students are expected to go on the trip, what would be the cheaper option?
Is there a certain number of students when the cost would be equal?
