Question

Determine if lines that pass through the given points are parallel, perpendicular or neither.
Line A: (5, 4) and (7, 5) Line B: (4, -5) and (8, -3)


A. Parallel
B. Perpendicular
C. Neither
D. Cannot be determined

Answer 1

You calculate both lines slopes using Rise/Run and then compare the slopes:

if the slopes are the same number then they are parallel lines
if the slopes are the inverse of one another then they are perpendicular

Answer 2

A. Parallel
