Concert Tickets: Tickets for a concert cost $10 each if you order them online, but you must pay a service charge of $8 per order. The tickets are $12 each if you buy them at the door on the night of the concert, with no service charge.
a. Write a system of equations to model the situation. Let c be the total cost. Let t be the number of tickets.
b. Graph the equations and find the intersection point.
Analysis: What does the intersection point of the system of equations you graphed in number 9 represent?

Vocabulary: How many solutions does an consistent and independent system have?
Writing: Suppose you graph a system of linear equations. If a point is on only one of the lines, is it a solution of the system? Explain.
Reasoning: Can a system of two linear equations have exactly two solutions? Explain.
Reasoning: Suppose you find that two linear equations are true when x = -2 and y = 3. What can you conclude about the graphs of the equations? Explain.
