1-7 Quiz The following questions are a review of what we covered today. They are designed to help you determine whether or not you understood the new concepts. Please make sure you make time to come and see me if you are missing more than you are getting right!

1. Find the distance between points P(8, 2) and Q(3, 8) to the nearest tenth. A. 11 B. 7.8 C. 61 D. 14.9

2. A high school soccer team is going to Columbus to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (3, 4) and the stadium in Columbus is at point (7, 1). The map shows a highway rest stop halfway between the cities. What are the coordinates of the rest stop? What is the approximate distance between the high school and the stadium? (One unit 6.4 miles.)

3. Find the coordinates of the midpoint of the segment whose endpoints are H(8, 2) and K(6, 10). A. (7, 6) B. (1, 4) C. (14, 12) D. (2, 8)

4. Noam walks home from school by walking 8 blocks north and then 6 blocks east. How much shorter would his walk be if there were a direct path from the school to his house? Assume that the blocks are square. A. 14 blocks B. 10 blocks C. 4 blocks D. The distance would be the same.

5. M(9, 8) is the midpoint of The coordinates of S are (10, 10). What are the coordinates of R? A. (9.5, 9) B. (11, 12) C. (18, 16) D. (8, 6)
