Determine If Two Lines Are Parallel or Perpendicular From Two Points

Two coplanar lines that never meet and are always an equal distance from each other.

• Parallel

• Perpendicular

• Intersecting

• Skew

Two coplanar lines that meet to form four right angles.

• Parallel

• Perpendicular

• Intersecting

• Skew

Determine if the lines through the given points are parallel, perpendicular, or neither.

(-1, 2) ; (3, -6) and (8, 5) ; (4, 3)

Slopes of perpendicular lines are...

• opposite reciprocals.

• opposites.
