Suppose we are given the following. Line 1 passes through (2, 2) and (4,7). -Line 2 passes through (-2,-2) and (2,8). Line 3 passes through (0, 7) and (-2, 2). (a) Find the slope of each line. Slope of Line 1- Slope of Line 2- Slope of Line 3= (b) For each pair of lines, determine whether they are parallel, perpendicular, or neither. Line 1 and Line 2: Parallel Perpendicular Line 1 and Line 3: Parallel Perpendicular Line 2 and Line 3: Parallel Perpendicular Neither Neither Neither
