Determine whether the line that passes through the two given points is parallel or perpendicular (or neither ) to a line with a slope of - 2. (6, 1), (8, 2)
A) parallel
B) perpendicular
C) neither

Question

Quizplus · Accepted Answer

The slope of the line passing through the points (6, 1) and (8, 2) is calculated as (2-1)/(8-6) = 1/2. A line is perpendicular to another if their slopes are negative reciprocals. Since -2 is the negative reciprocal of 1/2, the lines are perpendicular.
