  2. Essential Understanding When you reflect a figure across a line, each point of the figure maps to another point the same distance from the line but on the other side. The orientation of the figure reverses.

  3. Fold your graph paper into 4 equal parts • Draw a coordinate plane in each part • In box 1, draw a quadrilateral • Translate each vertex Right 2 Down 3 Ordered Pair: (x, y) Ordered Pair Rule: (x, y) → (x + h, y + k) h is horizontal shift k is vertical shift (x, y) → (x + 2, y – 3)

  4. Complete the following transformations on your remaining grids. Then describe the transformation. • (x, y) → (– x, y) • (x, y) → (x, – y) • (x, y) → (– x, – y) • (x, y) → (y,x) Reflection: y-axis Reflection: x-axis Rotation about the origin Reflection: y = x
