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:

Graph 1: A horizontal and vertical line intersect at 90°, so perpendicular.
Graph 2: Two lines with same direction, never intersect, so parallel.
Graph 3: Lines intersect but not at 90°, so neither.
Graph 4: Lines cross but not at 90°, so neither.

Answer:

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