Question

Given two lines, L1and L2,
with equal slopes and a line k that is
perpendicular to one of these two lines, L1. What
is the relationship between line k and the other
line, L2? *

Answer 1

Answer:

K and L2 are  perpendicular.

Step-by-step explanation:

Assume the slope of L1 is X. The slope of L2 is also X.

Using perpendicular slopes, the slope of K is -1/x, meaning it is perpendicular to both L1 and L2.
