are the two lines parallel, perpendicular, or neither? graph 1 graph 2 graph 3 graph 4 parallel parallel…

Explanation:

Step1: Recall line - relationship definitions

Parallel lines never intersect and have the same slope. Perpendicular lines intersect at a 90 - degree angle and the product of their slopes is - 1.

Step2: Analyze Graph 1

The two lines in Graph 1 never intersect. They have the same direction. So they are parallel.

Step3: Analyze Graph 2

The two lines in Graph 2 intersect but not at a 90 - degree angle. So they are neither parallel nor perpendicular.

Step4: Analyze Graph 3

The two lines in Graph 3 intersect but not at a 90 - degree angle. So they are neither parallel nor perpendicular.

Step5: Analyze Graph 4

The two lines in Graph 4 intersect at a 90 - degree angle. So they are perpendicular.

Answer:

Graph 1: Parallel Graph 2: Neither Graph 3: Neither Graph 4: Perpendicular
