Two points on L₁ and two points on L₂ are given. Use the slope formula to determine if lines L₁ and L₂ are parallel, perpendicular, or neither. L_1: (9, 2) and (3, -8)
L_2: (5, 5) and (-5, -1)

To determine if the lines are parallel, perpendicular, or neither, we need to find the slopes of each line. We can use the slope formula: slope = (y2 - y1) / (x2 - x1) For L_1:: slope = (-8 - 2) / (3 - 9) = (-10) / (-6) = 5/3 For L_2:: slope = (-1 - 5) / (-5 - 5) = (-6) / (-10) = 3/5 Since the slopes are not equal (not parallel) and not negative reciprocals (not perpendicular), the lines are neither parallel nor perpendicular. Hence the best choice is C, neither.
