David must install fencing around a lot that is shaped like a right triangle. The side of the that runs east to west is 20 feet long. The side
of the lot that runs north to south is 12.5 feet long. Calculate how many
feet of fencing is needed for the side that runs from the northwest to
the southeast side.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
