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: (-4, -7) and (1, 3)
L_2: (2, 6) and (5, 12)

The slope of the first line (L₁) is calculated using the points (-4, -7) and (1, 3), which gives a slope of (3 - (-7)) / (1 - (-4)) = 10 / 5 = 2. The slope of the second line (L₂) is calculated using the points (2, 6) and (5, 12), which gives a slope of (12 - 6) / (5 - 2) = 6 / 3 = 2. Since both lines have the same slope, they are parallel.
