Two points on L_1 and two points on L_2 are given. Determine whether L_1 is parallel to L_2, L_1 is perpendicular to L_2, or neither. L_1: (1, -2), (2, -3); L_2 (-2, -1), (-1, 0) parallel perpendicular neither

Solution

Dear Student Thak you for using Chegg for Line L1 Slope(m1) can be calculated as = (y2 - y1) / (x2 - x1) = ( -3 + 2) / (2 -1) = -1 for Line L2 Slope(m2) can be calculated as = (y2 - y1) / (x2 - x1) = ( 0 + 1) / (-1 + 2) = 1 Now since product of 2 slpes m1 * m2 = -1 Hence the given two lines must be perpendicular lines Solution
