Answer:
2/3
Explanation:
when a line is parallel to another line we say that the slopes are equal hence the slope of line e is 2/3.
NOTE: if a line is perpendicular to another the slope of line B the line is the negative reciprocal of the slope of Line A
for instance: if the slope was 2/3 the slope of the perpendicular line is -3/2
