Answer
Answer:
Graph 1: Parallel Graph 2: Neither Graph 3: Parallel Graph 4: Perpendicular
Explanation:
Step1: Recall parallel - line property
Parallel lines have same slope and never intersect. In Graph 1 and Graph 3, lines never intersect.
Step2: Recall perpendicular - line property
Perpendicular lines intersect at right - angles and product of their slopes is - 1. In Graph 4, lines intersect at right - angles.
Step3: Analyze Graph 2
In Graph 2, lines intersect but not at right - angles, so they are neither parallel nor perpendicular.
