1. Algebra 2 CP

2. Solve

5. Slope = m = 2 y-intercept = b = -9

6. Find the equation of the line that is perpendicular to the line below and goes through the point (6,-4)

8. Determine both the x and the y intercepts of the line below.

9. X-intercept = 40 Y-intercept = 5

10. Solve the equation below

11. x = -2 or x = -12

12. Solve

14. If Then -4 4

15. True

16. Solve

17. No solution! Remember the absolute value can never equal a negative

18. State a reasonable correlation coefficient

19. Answers Vary Must be positive and near one. r values in between 0.8 and 0.9 are good answers

20. Solve and graph your solution

21. Another acceptable format: AND Graph: (open circle on -4 and -2 with a segment in between connecting them)

22. Solve

25. All Real Numbers

26. Is this equation a model of direct variation?

27. No The line does not go through the origin

28. y varies directly with x. When x = 10, y is equal to 65. Write the equation that models this relationship and determine what y will be when x = 17.

30. Does the table below represent direct variation? Justify your answer. x-212 Y147-7-14

31. Yes. One justification: Y divided by x is always equal to a constant, -7. Another possible justification: Show that the slope is -7 and that the y-intercept is 0. Since the data forms a line through the origin, it is direct variation.

32. Solve the equation below

33. x = -4

34. Solve the equation below for I.

37. Another acceptable format:

38. Solve

40. Write the equation of the line that has a slope of 0 and contains the point (4, 9)

41. y = 9

42. Write the equation of the line in standard form that contains the point (9, -1) and is parallel to the line below.

44. Write the equation for the line shown in the graph below

46. Solve the absolute value inequality:

48. Solve the equation below for b

50. Solve the absolute value inequality below

51. No real solution. Absolute value can never be less than a negative number. Test Prep Tips: Focusing on completing practice problems rather than just looking over problems. You can retry problems from your notes and/or HW. For HW, focus on the ones that you initially got incorrect or got stuck on. Also, Chapter 1 review solutions can be found in the back of the book.
