Identifying parallel and perpendicular lines from coordinates Suppose we are given the following. Line 1 passes through (-7, -2) and (0, 3). Line 2 passes through (0, 1) and (-5, 8). Line 3 passes through (0, -3) and (7, 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: OParallel Perpendicular ONeither Line 1 and Line 3: OParallel O Perpendicular ONeither Line 2 and Line 3: OParallel Perpendicular ONeither Explanation Check O M
