#y=|3x+6|# represents the pair of lines #y=+-(3x+6)#. The common point is #(-2, 0)#. Another point on the first line is #(0, 6). (0, -6)# is on the second line.

Explanation:

#y=|3x+6|# is the combined equation for the pair of straight lines #y++-(3x+6)#.

Solving, the point of intersection is #(-2. 0)#.

Another point on the first line is #(0, 6). (0, -6)# is on the second line.
