Warm Up Graph triangle ABC . A (-2, 4), B (0, 6), C (3, -3) Reflect triangle ABC across the x axis. Write the ordered pairs. Reflect triangle ABC across the y axis. Write the ordered pairs.

Warm Up Answers Original – Black Reflection across the x-axis- blue A’(-2, -4), B’(0, -6), C’ (3, 3) Reflection across the y-axis - red A(2, 4), B(0, 6), C’(-3, 3)

On a coordinate plane map, the gym is located at (-2, 5). The middle school is located at (7, 5). If each unit represents one block, how far will Jim have to walk from the school to the gym?

On a coordinate plane map, the park is located at (-1, 3) On a coordinate plane map, the park is located at (-1, 3). Joshua’s house is located at (-1, -8). If each unit represents one block, how far will Joshua have to walk to go to the park?

On a coordinate plane map, Kim’s house is located at (-6, 5) On a coordinate plane map, Kim’s house is located at (-6, 5). Karen’s house is located at (-6, -4). The shopping mall is located at (7, -4). How far will Kim travel if she leaves her house, picks up Karen and then goes to the mall?

Closure On a coordinate plane Lily’s house is located at (-3, 5). John’s house is located at (3, 5). Lily and John are going to Caleb’s house which is located at (3, -2). How far will Lily walk if she goes by to get John on the way to Caleb’s house? 13
