17. Tuesday, Sept 27 Lesson 5.1 Integers and Graphing

18. Objective: To use integers to represent real world situations.

19. Integers and Graphing Integers are all positive whole numbers and their opposites and zero.

20. Integers and Graphing Integers are all positive whole numbers and their opposites and zero. Negative numbers are used to represent data less than 0. A negative number is written with a “-” sign.

21. Integers and Graphing Integers are all positive whole numbers and their opposites and zero. Negative numbers are used to represent data less than 0. A negative number is written with a “-” sign. Positive numbers are used to represent data greater than 0. If a number does not have a “-” sign, it is assumed to be positive.

22. Integers and Graphing We can use a number line to display all integers. Integers less than zero Integers greater than zero are negative integers are positive integers

35. Integers and Graphing A gain of $2 a share would be written as what integer?

36. Integers and Graphing A gain of $2 a share would be written as what integer? Because it represents a gain, the integer would be +2, or just 2.

37. Integers and Graphing A gain of $2 a share would be written as what integer? What would zero represent in this situation?

38. Integers and Graphing A gain of $2 a share would be written as what integer? What would zero represent in this situation? No change in the value of the share.

39. Integers and Graphing Ten degrees below zero would be written as what integer?

40. Integers and Graphing Ten degrees below zero would be written as what integer? Because it represents a number below zero, the integer would be -10.

41. Integers and Graphing Ten degrees below zero would be written as what integer? What would zero represent in this situation?

42. Integers and Graphing Ten degrees below zero would be written as what integer? What would zero represent in this situation? Zero degrees.

43. Integers and Graphing A bank account overdrawn by $20 would be written as what integer?

44. Integers and Graphing A bank account overdrawn by $20 would be written as what integer? Because it represents a number below zero, the integer would be -20.

45. Integers and Graphing A bank account overdrawn by $20 would be written as what integer? What would zero represent in this situation?

46. Integers and Graphing A bank account overdrawn by $20 would be written as what integer? What would zero represent in this situation? Zero money in the bank account.

47. Integers and Graphing Integer and sets of integers can be graphed on a number line.

48. Integers and Graphing You will need the number lines I handed out yesterday. When drawing on these number lines, draw lightly. This will be used for several weeks.

49. Integers and Graphing Graph -7 on the number line. To graph an integer on the number line, start at zero.

50. Integers and Graphing Graph -7 on the number line. To graph an integer on the number line, start at zero.

51. Integers and Graphing Graph -7 on the number line. Move to the left for a negative integer and right for a positive integer.

52. Integers and Graphing Graph -7 on the number line. Move to the left for a negative integer and right for a positive integer.

53. Integers and Graphing Graph 6 on the number line.

54. Integers and Graphing Graph 6 on the number line. The dot is 6 spaces to the right of zero, or +6.

55. Integers and Graphing Graph -11 on the number line.

56. Integers and Graphing Graph -11 on the number line. The dot is 11 spaces to the left of zero, or -11.
