Slopes of Lines Section 3-3

Definition of Slope The slope m of a line containing 2 points with coordinate (x1, y1) and (x2, y2) is given by the formula: )

Postulate 3-2 and 3-3 2 nonvertical lines have the same slope iff they are parallel. 2 nonvertical lines are perpendicular iff the product of their slopes is –1.

undefined slope zero slope positive slope negative slope
