Question

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

Explanation:

Step1: Analyze Graph 1

Check if lines intersect at 90° (perpendicular) or same slope (parallel). Graph 1 lines cross but not at 90°, so neither.

Step2: Analyze Graph 2

Lines are horizontal and vertical, intersect at 90°, so perpendicular.

Step3: Analyze Graph 3

One line is vertical, the other has a slope (not vertical/horizontal), so neither (not parallel, not 90°).

Step4: Analyze Graph 4

Lines have same slope (never meet), so parallel.

Answer:

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