Write the equation of a line Y-intercept (0, b) Slope-intercept y = mx + b Replace m and b into the equation Slope m Point Point (x1 , y1) (x2 , y2) Point-slope y y1 m x x1 Replace m and (x1 , y1 ) into the equation 1. Find the slope y y1 m 2 x 2 x1 2. Pick a point as (x1 , y1 ) 3. use Point-slope form y y1 m x x1 If two lines are parallel to each other, their slopes are the same. If two lines are perpendicular to each other, their slopes are opposite reciprocals.
