Problem 354

Geometry Difficulty 2.0 Find the answer CEMC Fermat · Canada · 2006

The points (5,3)(5, 3) and (1,−1)(1, -1) are plotted on a sheet of graph paper. The sheet of graph paper is folded along a line so that the point (5,3)(5, 3) lands on top of the point (1,−1)(1, -1). The equation of the line that represents the fold is (A) y=−x+1y = -x + 1 (B) y=−x+2y = -x + 2 (C) y=−x+3y = -x + 3 (D) y=−x+4y = -x + 4 (E) y=−x+5y = -x + 5
