1 Class: Date: Elizabeth Blackwell MS 210Q- 8th Grade Mid-Winter Recess Assignment The following assignment has been provided for students for the Winter Recess.. Please assist your child in completing this assignment and have him/her bring it to school on Monday, February 24, Parent/Guardian Signature Multiple Choice Identify the choice that best completes the statement or answers the question.show all work on loose leaf paper and attach to this page. 1. The graph represents the number of students graduating from colleges and how much they make in the first year in Identify any clusters in the graph. Which statement below describes any clusters? A. There is a cluster between 10 and 20 graduates and between 20 and 30 B. There is a cluster between 13 and 44 graduates and between 20 and 43 C. There is a cluster between 10 and 30 graduates and between 10 and 20 D. There are no clusters in the graph. 2. Gino incorrectly said that 711 = Use a property of exponents to simplify correctly. 7 What was Gino's likely error? A. He subtracted the bases and the C. He added the exponents. exponents. B. He subtracted the exponents incorrectly. D. He subtracted the bases instead of the exponents. 1

2 3. A scatter plot suggests a linear association among the data. Two points that lie on the trend line drawn for the data are (2,12) and (4,16). Find the equation for the trend line. A. y=2x+7 C. y=x +9 B. y=x+7 D. y = 2x If figure ABCD is translated so that the image of A is A at ( 2, 2), then what will the coordinates of the image of C be after the translation (that is, C )? A. ( 2, 0) C. ( 1, 3) B. (1, 2) D. (1, 3) Short Response Show all work on loose leaf paper and attach to this page. 5. Divide. Express your answer in scientific notation Express the slope of the line below. 2

3 7. Consider the scatter plot shown. Are there any points that are outliers? If so, Identify them and explain why it is an outlier. 8. In the diagram below, PQ is parallel to RS. a. Label another angle whose measure is 76. b. Explain how you know this angle has the same measure. 9. Use the graph below to answer the following questions: a. If figure ABCD is translated so that the image of A is A at ( 3, 1), then what will the coordinates of the image of D be after the translation (that is, D )? b. Describe a rule that translates any point of figure ABCD so that the image of A is A. 3

4 10. Consider this figure: For each of the following transformations, match the original figure with the correct image below. a. reflection in the y-axis b. Ê Á x, y ˆ Ê Á x, y ˆ c. translation right 5 units and down 5 units d. Ê Á x, y ˆ Ê Á x, y 5 ˆ 4

5 11. Plot the points (2, 4), (3, 5), (5, 5), (4, 4), (5, 3), and (3, 3) on a coordinate grid. Form a polygon by connecting the points in order and then connecting the last point to the first point. Reflect the polygon in the y-axis. Then translate the image 3 units to the right and 2 units down. Finally, rotate the second image 90 about the origin. What are the coordinates of the vertices of the final image? 12. You ask 98 of your classmates what their favorite season is. Complete the two-way frequency table to show the results of the survey. Write 2 true statements based on the data in the table. 5
