To use the tree house as the start of the zip line the cable needs to be attached to the starting tree at a height 16 feet above the ground. To meet the slope constraint Vince wants to change the height 7 feet and end the zip line at a height 9 feet above the ground. He claims this vertical
change meets the slope constraint.
Test Vince's claim for Tree A and Tree B. Use specific numbers from the situation to justify or refute whether having a vertical change of 7 feet will satisfy the slope constraint for each tree.
