Question

Identify the lines below as parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is 2/5.

(3 points)
line n, with slope -5/2
line m, with slope 5/2
line p, with slope 2/5

Answer 1

Explanation:

Line n is neither parallel nor perpendicular to the given line, since their slopes are not negative reciprocals (the slopes are -5/2 and 2/5, respectively).

Line m is neither parallel nor perpendicular to the given line, since their slopes are not negative reciprocals (the slopes are 5/2 and 2/5, respectively).

Line p is parallel to the given line, since they have the same slope (2/5).
