Tell whether the lines through the given points are parallel, perpendicular, or neither. 3. Line 1: (2, 3), (4, 12) Line 2: (5, 10), (14,8)

Perpindicular

Step-by-step explanation:

Use the Slope formula to find the Slope of the line through each pair of points.

y2 - y1 / x2 - x1

12 - 3 / 4 - 2 = 9/2 is the first Slope.

8 - 10 / 14 - 5 = -2/9 is the Slope of the second line.

The slopes are negative reciprocal, perpendicular.
