    Statement Justification The coordinates of point D are (4, 5) and coordinates of point E are (5, 3) Midpoint Formula Length of segment DE is Square root of 5 and length of segment AC is 2 multiplied by the square root of 5. Segment DE is half the length of segment AC. Substitution Property of Equality Slope of segment DE is −2 and slope of segment AC is −2. Slope Formula Segment DE is parallel to segment AC. Slopes of parallel lines are equal.
