Back

Perpendicular Lines

Front

Determine if the lines represented by the equations -6x + y = 2 and 6x + y = 2 are parallel, perpendicular, or neither.

Back

Neither

Front

Determine if the line segments represented by the equations are parallel, perpendicular, or neither: y = -2/3x + 2 and y = 3/2x + 9.
