Document Summary

Parallel lines: if two lines are parallel, they have the same slope. Parallel lines are two distinct lines in the same plane that do not intersect. Perpendicular lines: if two lines are perpendicular, their slopes are negative reciprocals of each other. If m1 is slope of one line and m2 is slope of line perpendicular, then m1m2 = -1. 1: determine if the lines are parallel, perpendicular, or neither. 2: write the equation of the line given the following: parallel to the line y = -3x; containing the point (-1, 2). Express in point- slope form. b) perpendicular to the line y = 5; containing the point (4, 2). Express in standard form: perpendicular to the line x - 3 y = 4; containing the point (-2, 0). Express in slope-intercept: containing the point (6, -5) and parallel to 3x + 2y = 8.
