Are the given lines, parallel, perpendicular, or neither. Explain.

x = 1, and y = 0

• Parallel, they have the same slopes.

• Perpendicular, because their slopes are opposite reciprocals.

• Neither, because their slopes are not the same and are not opposite reciprocals.

• Neither, because their slopes are zero.
