Reflect Across a Horizontal Line Graph the quadrilateral after a reflection across the line. Then write the ordered pairs for the new vertices. Answer: The ordered pairs for the new vertices are (3, 7), (3, 9), (5, 9), and (7, 7).

Reflect Across a Horizontal Line You can check the reasonableness of the vertices by drawing the quadrilaterals on grid paper. When the paper is folded, they should match exactly.
