5. Joe and Mike each own their own plumbing repair company
Joe and Mike each own their own plumbing repair company. The total labor costs c for
a repair that takes h hours are listed in the tables.
Based on the information in the table, which statement is NOT true?
Mike’s Plumbing is cheaper for a two-hour repair.
A three-hour job costs the same with both companies.
Joe’s Plumbing is more expensive for a one-hour repair.
A four-hour job is cheaper with Mike’s plumbing
Plumber Joe

6. Let’s graph these lines!
4) Complete each step to solve the system of linear equations 3x+4y=18 and x+3y=11.
Make a table of values for each linear equation. Include at least three rows of the table.
Be sure to label each table.
b. Use at least two points to graph each line. Label each point. Label each line.
3x + 4y = 18
x + 3y = 11 2 -2 6 x y x y -4 5 2
Let’s graph these lines!

7. Line 1
Line 2 x y x y
c. What is the solution to the system of linear equations ?

8. Let’s do
a happy dance!
Last question!
#5. A math test is made up of 5-point questions and 10-point questions. There are 24 questions on the test. The total number of possible points is 150 points. a.) Write a system of linear equations to represent the problem. Use f for 5-point questions and t for 10-point questions. b.) Find the intercepts of the graph of each equation you wrote in part a. State your answers in complete sentences.
x intercept
y intercept
x intercept
y intercept

9. y 10 point questions (t) x 5 point questions (f)
c.) Use the intercepts from part b to graph the system of linear equations.
Label each axis to show
what it represents.
Label each line.
10 point questions (t) x
5 point questions (f)
d. What is the total value of all the 10-point questions on the test? Explain how you know.
