7. A charity club had a fundraising event and after selling 200 tickets they made $12,000 in profit. After selling 500 tickets they had $30,000.

Assuming the tickets can be written as a linear function, write a linear function for the profit, P(t) for t tickets.

Interpret the meaning of the slope and the y intercept in the context of the problem.

How many tickets would they have sold if they made $1500.00?

1: X & Y Intercepts a) A student says that the x-intercept of the

graph x + 2y = 5 is the point (0, 5). Why is the student incorrect?

b) Find the x and y intercepts ad graph.

3: Word ProblemBeach Bike rentals charges $5 plus an additional $0.20 per mile to rent a bicycle. a) Write and graph an equation for the total cost

of renting a bicycle, y, after riding for x miles. b) How much would Beach Bike Rentals charge

you for riding 6 miles? c) If you only have $10,000, what is the maximum

number of miles you can ride?d) State domain and range the context of this

situation

4: Equations of a Line
