Lines a and b are parallel line cis perpendicular to both line a and line b. which statement about lines a, b, and is not true? clearch line a and line b have the same slope. the sum of the slopes of line b and line cis 0. the product of the slopes of line cand line bis -1. the product of the slopes of line a and line cis -1.

  see below

Step-by-step explanation:

The slopes of parallel lines are the same. The slopes of perpendicular lines are negative reciprocals of each other, hence their product is -1.

___

For the most part, the concept of adding slopes of lines does not relate to parallel or perpendicular lines in any way.

step-by-step explanation:

see if this :

the answer is c

hope this !
