The slope of a line is given.
a. Determine the slope of a line parallel to the given line, if possible.
b. Determine the slope of a line perpendicular to the given line, if possible.
-$$m = \frac { 8 } { 5 }$$
A) a. $m = 0 ;$ b. $m = \frac { 5 } { 8 }$
B) a. $m = \frac { 8 } { 5 } ;$ b. $m = - \frac { 5 } { 8 }$
C) a. $m = \frac { 8 } { 5 } ;$ b. $m = \frac { 5 } { 8 }$
D) a. $m = 0 ;$ b. $m = - \frac { 8 } { 5 }$

Question

Quizplus · Accepted Answer

Lines parallel to a given line have the same slope, so the slope remains $ \frac{8}{5} $. Lines perpendicular to a given line have a slope that is the negative reciprocal of the given line's slope, so the slope is $ -\frac{5}{8} $.
