  1. Are You Smarter Than a Fifth Grader?

  2. Stay focused and work out each problem in your notebooks

  3. Copy problems into your notebook and SHOW ALL of your work!!

  4. The review is only as good as you make it…..so make it your best!

  5. Determine whether the relationship between the two quantities described in each table is linear or not AND explain why. Yes, they have the same common difference (+1.6)

  6. The table below shows the average rate of increase in a nurse’s salary over the past 20 years. Explain whether the growth in salary is linear. Yes…all the rates of change are the same

  7. Find the slope of the line in the diagram below: -1/10 = -0.1

  8. Find the slope between the points (5, 3) and (-2, 8) -5/7 = 5/-7

  9. What is the rate of change for the function shown below:

  10. What is the rate of change for the function represented In the table? -2 0 2 ½ c

  11. Jimbo Jones spent $46.50 on 3 T-shirts. The next time he spent $31.00 on two T-shirts. What is the cost for one T-shirt? $15.50

  12. State the slope and y-intercept for each equation: Y = 5x – 1 y = 0.3x 3x + y = 6 Slope = 0.3 Y-int. = 0 Slope = -3 Y-int. = 6 Slope = 5 Y-int. = -1

  13. Write an equation in slope-intercept form for the graph shown:

  14. State the x-intercept and y-intercept of the graph below: X-int. = 6 Y-int. = -9

  15. State the x- and y-intercepts of the equation: 5x + 4y = -20, AND sketch the graph using the intercepts x-int. = -4 y-int. = -5

  16. Monty has a total of $290 in ten and five dollar bills. This can be represented by the function 10x + 5y = 290. Interpret the x- and y-intercepts. The x-intercept of 29 represents the number of $10 bills There would be if there were zero $5 bills. The y-intercept of 58 represents the number of $5 bills There would be if there were zero $10 bills.

  17. Solve the system of equations by graphing: (-2, -2)

  18. Julie has 81 pieces of jewelry. She has twice as many earrings as she has necklaces. Create and solve a system of equations to find out how many earrings And necklaces she has. x + y = 81 Y = 2x Solution: 27 necklaces, 54 earrings

  19. Solve the following system of equations by substitution: X = -4 and Y = -8

  20. Solve by substitution: (x, y) = (4, -7)

  21. What are you going to do to prepare for the Chapter 6Test? • Review my notes • Do homework problems over again • Study with my parents or friends • All of the above • wait until tonight and think about studying
