Point B′(1, 4) is the image of B(3, 2) after a reflection in line c. Write an equation for line c.
line c is the perpendicular bisector of B’ and B
Step 1: Find the midpoint of B and B’
It is (2, 3)
Step 2: Find the slope of line through B and B’
It is -1, hence slope of the perpendicular bisector should be 1
Equation of the line c is
