Example 5: Writing the Equation of a Perpendicular Line. Line l1 has an equation of y = -2x + 1. Find the equation of a line l2 that passes through P(4, 0) and is perpendicular to l1. First you must find the slope, m2. m1 \u2219 m2 = \u2219 m2 = -1. m2 = \u00bd. Then use m = \u00bd and (x, y) = (4, 0) to find b. y = mx + b. 0 = \u00bd(4) + b. 0 = 2 + b. -2 = b. So, an equation of l2 is. y = \u00bd x - 2.", "Image XResolution": "200", "Image YResolution": "200", "Image ResolutionUnit": "Pixels/Inch", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
