Lesson 5: Practice Problems

Problem 1

  1. Here are some points.

    What are the coordinates of , , and after a translation to the right by 4 units and up 1 unit? Plot these points on the grid, and label them , and .

    Three points labeled, A, B, and C, plotted on a coordinate grid with the origin labeled “O.” The x axis has the numbers negative 10 through 8 indicated. The y axis has the numbers negative 4 through 6 indicated. Point A is located at negative 6 comma 5. Point B is located at 3 comma 2. Point C is located at 0 comma negative 1.
  2. Here are some points.

    What are the coordinates of , , and after a reflection over the -axis? Plot these points on the grid, and label them , and .

    Three points labeled , D, E, and F, are plotted on a coordinate grid with the origin labeled “O.” The x axis has the numbers negative 5 through 5 indicated. The y axis has the numbers negative 2 through 3 indicated. Point D is located at negative 3 comma 3. Point E is located at 5 comma 0. Point F is located at 2 comma negative 2.
  3. Here are some points.

    What are the coordinates of , , and after a rotation about by 90 degrees clockwise? Plot these points on the grid, and label them , and .

    Three points labeled, G, H, and I, are plotted on a coordinate grid with the origin labeled “O.” Thex axis has the numbers negative 5 through 5 indicated. The y axis has the numbers negative 3 through 5 indicated. Point G is located at negative 1 comma 3. Point H is located at negative 4 comma 0. Point I is located at 3 comma negative 2.
