  1. Chapter 8 Test Review Lessons 8-5 to 8-10 and Graphing Inequalities

  2. Question #1 • The cost of meat varies directly with the number of pounds bought. Suppose 2 pounds cost $9.50. a. Write an equation that could be used to find the unit cost of meat. b. Find the cost of 5 pounds of meat.

  3. Question #2 • Find the slope of the line that passes through each pair of points. • C (4,5) and D (-3,5) • Name 2 points that have a slope of 2.

  4. Question #3 • Use the equation 2x + 4y = -6. A. State the slope and the y-intercept for the graph of the equation. B. Graph the equation using slope and y- intercept.

  5. Question #4 • Write an equation in slope-intercept form to represent the table values.

  6. Question #5 • Solve the system of equations by graphing. y= -2x + 1 y= 3x -4

  7. Question #6 • Solve each system of equations by substitution. y + x =8 x = y-3 y = 2x + 2 2x + y =6

  8. Question #7 • To replace a set of brakes, an auto mechanic charges $40 for parts plus $50 per hour. The total cost y can be given by y=50x + 40 for x hours. • Graph the equation using the slope and y-intercept. • State the slope and y-intercept of the graph of the equation and describe what they mean.

  9. Question #8 • The cost of 2 bagels and 2 cans of orange juice is $4.40. The cost of 3 bagels and 4 cans of orange juice is $7.80. • A. Write a system of equations to represent this situation. • B. Solve the system of equations by substitution. Explain what the solution means.
