Answer:
E: L is perpendicular to a line with slope  .
.
Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of  is
 is  (remember, to get the reciprocal, simply switch the numerator and the denominator).
 (remember, to get the reciprocal, simply switch the numerator and the denominator).
So, the negative reciprocal of  is
 is  . This represents the slope of a line that is perpendicular.
. This represents the slope of a line that is perpendicular.
