Question

1. write the correct vocabulary and corresponding equations from the word box in the table below.

graph type of lines
word box
coincident parallel perpendicular skew

Explanation:

Parallel lines are lines in a plane that never intersect and have the same slope. Perpendicular lines intersect at a 90 - degree angle and the product of their slopes is - 1. The first graph shows non - intersecting lines which are parallel. The second graph shows lines intersecting at 90 degrees which are perpendicular.

Answer:

First row (parallel lines graph): Parallel
Second row (perpendicular lines graph): Perpendicular
