Lauren Nitahara Calculus Notes Chapter P1 What do we know about lines? - Slope: m = rise  =  y  =  y 2  – y 1         run      x    x 2  – x 1 - Two Points: x 1  y x 2   y 2 - Equations of Lines: Slope-Intercept Form y = mx + b < if given line Point-Slope Form y – y 1  = m (x – x 1 )  < if making line General Form Ax + By + C = 0 Definition: Two non-vertical lines are parallel  if and only if their slopes are equal * Slope of a vertical line is undefined Definition: Two non-vertical lines are perpendicular

Unformatted text preview: if and only if their slopes are negative reciprocals of each other * If given m 1 then m 2 = -1 m 1 Ex: Find the equation of the line that passes through (1,4) and is parallel to 2x 3y = 5 Ex. Find the equation of the line that passes through (1,4) and is perpendicular to 2x 3y = 5 Summary: General Form Vertical Line Horizontal Line Point-Slope Form Slope-Intercept Form...
