Homer sells tickets for admission to your school play and collects a total of $104. Admission prices are $6 for adults and $4 for children. He sold 21 tickets total. Solve the system:
x + y = 21
6x + 4y = 104

• (10, 11)

• (12, 9)

• (11, 10)

• (9, 12)

What are systems of linear equations?

• a set of two or more linear equations in the same variables

• a polynomial with three terms

• set of two or more linear inequalities in the same variables

Type the solution as an ordered pair, (x, y).

At the zoo I saw 11 animals. Some of the animals were pigs and others were chicken. There were 28 legs. Write a system of linear equations to represent this situation.

• c + p = 28

  4c + 2p = 11

• c + p = 11

  4c + 2p = 28

• c + p = 11

  2c + 4p = 28

• c + p = 28

  2c + 4p = 11

• 8 chickens and 3 pigs

• 9 pigs and 2 chickens

What is the y-intercept?
