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.
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 90o angle) • They are negative reciprocals
