for each graph, decide if the two lines are parallel, perpendicular, or neither. graph 1 graph 2 graph 3 graph 4 parallel parallel parallel parallel perpendicular perpendicular perpendicular perpendicular neither neither neither neither
Answer
Explanation:
Step1: Recall line - relationship rules
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 intersect at an angle other than 90 degrees. So they are neither parallel nor perpendicular.
Step3: Analyze Graph 2
The two lines never intersect and are always the same distance apart. They are parallel.
Step4: Analyze Graph 3
The two lines intersect at an angle other than 90 degrees. So they are neither parallel nor perpendicular.
Step5: Analyze Graph 4
The two lines never intersect and are always the same distance apart. They are parallel.
Answer:
Graph 1: Neither Graph 2: Parallel Graph 3: Neither Graph 4: Parallel
