How to Write Equation of Parallel and Perpendicular Lines?
Algebra 1 Parallel and Perpendicular Lines Two slope facts unlock this topic: parallel lines have the same slope, and perpendicular lines have slopes that are negative reciprocals (their product is \(-1\)). With those, you can write a line parallel or perpendicular to any given line. We’ll do both, with a solver, practice, and a worksheet […]
