Answer:

E: L is perpendicular to a line with slope $-\frac{3}{2}$ .

Lines are perpendicular if the negative reciprocal of the slope is equal. For example, the reciprocal of $\frac{2}{3}$ is $\frac{3}{2}$ (remember, to get the reciprocal, simply switch the numerator and the denominator).

So, the negative reciprocal of $\frac{2}{3}$ is $-\frac{3}{2}$ . This represents the slope of a line that is perpendicular.
