Math 1021 Section 2.4  Parallel and Perpendicular Lines 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 m 1 is slope of one line and m 2 is slope of line perpendicular, then m 1 m 2 = -1 Ex. 3 and –1/3 Ex. 1:   Determine if the lines are parallel, perpendicular, or neither. 2x – y = 5             8x + 4y = -9

Unformatted text preview: Ex. 2: Write the equation of the line given the following: a) 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. c) perpendicular to the line x - 3 y = 4; containing the point (-2, 0). Express in slope-intercept. d) containing the point (6, -5) and parallel to 3x + 2y = 8. Express in standard form. Use integers as coefficients....
