1. Imagine driving down a mountainside. You see a sign indicating there is a 12% grade. Approximate the amount of horizontal change in your position if you note from elevation signs that you have descended 2000 feet vertically. Use the embedded equation editor in Blackboard to show steps on how the approximation was calculated.

2. Determine whether the lines L1 and L2 passing through the pairs of points are parallel, perpendicular, or neither. If they intersect state the point of intersection as an exact ordered pair. Show all calculations using the embedded equation editor.

a. L1: (0,-1), (5,9)

L2: (0,3),(4,1)

b. L1: (-2,-1), (1,5)

L2: (3,5),(5,9)

(I dont understand how to do this)
