10) Tell whether the slope of AB is parallel, perpendicular, or neither to the
slope of CD. A(-3, 2) and B(2, 4) C(4, 0) and D(6,-5)

AB slope is 2/5, CD slope is -5/2; Neither
AB slope is 2/5, CD slope is -5/2; Parallel
AB slope is 2/5, CD slope is -5/2: Perpendicular
AB slope is -5/2, CD slope is 2/5; Parallel
