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
(remember, to get the reciprocal, simply switch the numerator and the denominator).
So, the negative reciprocal of is
. This represents the slope of a line that is perpendicular.
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent
When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
