The slope of line 1 is -1/2 and line 1 is parallel to line2. what is the slope of line2?

a.
m = –2
b.
m = -1/2
c.
m = 1/2
d.
m = 2

; '

Parallel lines have the same slope! The slope measures how steep the line is, and parallel lines are equally steep.

It follows quite immediately that line 2 has also slope -1/2.
