p. 30 Distance, Midpoint and Slope Midpoint: equal distance from each endpoint of the segment (the average between the two points) Formula: Distance Formula: Slope: or If two lines have the same slope, they are parallel. If two lines have opposite slope, they are perpendicular. (They are negative reciprocals)

p. 30 Distance, Midpoint and Slope If two lines have the same slope, they are parallel. (Lines never intersect) If two lines have “opposite” slopes, they are perpendicular. (Lines intersect at 90 o angle) They are negative reciprocals
