Question: Consider the points A(-2, 2) B(2, 8) C(-4, -4) & D(0,4). Are lines AB and CD parallel? Two ships leave the same island port

Consider the points A(-2, 2) B(2, 8) C(-4, -4) & D(0,4). Are lines AB and CD parallel? Two ships leave the same island port at the same time. Ship A is traveling north at 20 miles per hour. Ship B is traveling east at 30 miles per hour. How far apart are ships A and B 2 hours after they leave port? A rancher has 1500 feet of fence and would like to enclose a rectangular area that borders a river that forms a straight edge for one of the sides of the rectangle. The edge of the rectangle along the river does not need to be fenced. If X is the length of the side of the rectangle opposite the river edge, write an expression in X that calculates the total square feet of the rectangle.
