Geometry Angles and Intersecting Lines Angles Between Intersecting and Parallel Lines 1 Answer VinÃcius Ferraz Dec 10, 2015 y = -2x + 13 Explanation: r: y = ax + b is perpendicular to s: y = -1/a + c Your r has a = 1/2. (4,5) in s: y = -2x + c 5 = -2 * 4 + c c = 13 Answer link Related questions When given line y=2x + 3 and point (4,2), how would you find a parallel and a perpendicular line?
