Question 120644: 3. Geometry. Floor plans for a building have the four corners of a room located at the
points (2, 3), (11, 6), (-3, 18), and (8, 21). Determine whether the side through the
points (2, 3) and (11, 6) is parallel to the side through the points (-3, 18) and (8, 21).
Slope of the line through the points (-3, 18) and (8, 21)
Answer: Slope is
Since the slope of the line through (2, 3) and (11, 6) is and the slope of the line through (-3, 18) and (8, 21) is this means the two slopes are not equal. So this means that the two lines are not parallel.
