Slope of Parallel and Perpendicular Lines

What are Parallel Lines? Two lines in the same plane that intersect to form right angles. Two lines in the same plane that will never intersect, have the same slope. Two lines in different planes that will never intersect. Two lines in the same plane that intersect. What are perpendicular lines? Two lines in the same plane that will never intersect, have the same slope. Two lines in the same plane that intersect to form right angles. Two lines in different planes that will never intersect. Two lines in the same plane that intersect. Find the line that is parallel to the original. y= 2x-2 y=2x+1 y=-2x y= -2x+5 y= -1 y= -1 y= 2 y= 2 y= 1 y= 1 y= -3 y= -3 Find the line that is perpendicular to the original. y= 4x+2 y= -1 y= 4 y= -3 y= -1 y= 4x-3 y= -3 y= 4 y= -4 y= 3 y= 3 y= -4 Determine if the lines are parallel, perpendicular, or neither. Parallel x-2y = 2 and 2x-4y = 7 y=-3 and 3x+4y = 3 y= -1 and y+2 = -1 Perpendicular x=5 and y=7 2x+3y = 7 and 6x-4y = 10 y= 4 and y= -3
