Question

for each graph, decide if the two lines are parallel, perpendicular, or neither.
graph 1
graph 2
graph 3
graph 4
parallel
perpendicular
neither
parallel
perpendicular
neither
parallel
perpendicular
neither
parallel
perpendicular
neither

Explanation:

• Graph 1: The lines intersect but do not form right angles, and their slopes are not equal, so they are neither parallel nor perpendicular.
• Graph 2: The lines intersect at a right angle (90 degrees), so they are perpendicular.
• Graph 3: The lines run side by side and never intersect, so they are parallel.
• Graph 4: The lines intersect at a right angle (one horizontal, one vertical), so they are perpendicular.

Answer:

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