1. Interim Review – The next Interim is January 10 (Standard 13-27) 1.Jacqueline got a paycheck for $550. She loaned her mom $145 and bought groceries worth $170. If she already had $80 in the bank, how much does she need back from her mom in order to pay her rent which is $400. 2.List all the positive factors of 18. 3.If x = ½, what is the value of 3x – 2? x 4. What is the value of |5 – x| if x = 8? 5. If the probability that it will rain tomorrow is.8, what is the probability that it will not rain tomorrow? 6. What is the least common multiple of 10, 20, and 40 ? 7. Simplify 12a – 4b + 6a – 3b

2. Objectives: By the end of this class period, with an 85% accuracy, students will be able to:  Describe what is happening in graphs of relations

3. A. The length of the side is independent, and the the area of the square is dependent. B. The area is independent, and the side length is dependent. C.Both variables are independent. D.Both variables are dependent. B. The area of a square increases as the length of a side increases. Identify the independent and dependent variable in this relation.

4. A relation can be graphed without a scale on either axis. These graphs can be interpreted by analyzing their shape. See p. 42 Example 3 See graph Y depends on x. The distance depends on the time. Distance – dependent and time - independent As the time increases the distance increases until the graph becomes a horizontal line. Time increases but the distance remains the same. At this section, she stopped. Then she continued to ride her bike.

5. Analyze Graphs The graph represents the temperature in Ms. Coleman’s classroom on a winter school day. Describe what is happening in the graph. (y) Temperature depends on the (x) time. Temperature – dependent and time independent Sample: The temperature increases after the heat is turned on. Then the temperature goes up and down because of the thermostat. Finally, the temperature drops when the heat is turned off. Example:

6. A.Macy is doing bobs. B.Macy’s speed increases as she crosses the length of the pool, but then decreases to zero when she turns around at the end of each lap. C.Macy is swimming at a constant speed. D.Macy’s speed continues to decrease. The graph represents Macy’s speed as she swims laps in a pool. Describe what is happening in the graph.
