Question

ADEF has coordinates given by D = (2,7), E = (3,4), and F = (-1,-2). Marcus reflects ADEF across an

unknown line. E' stays in the same position, and D' = (4,7). (The use of the graph paper below is optional).

Josh says ADEF is reflected across a horizontal line. Do you agree with Josh? Explain why or why not.

Find the coordinates of F'?
