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 […]
Parallel, Perpendicular, and Intersecting Lines
Kinds of Lines Horizontal Lines – Lines mapped from left-to-right or right-to-left and which are parallel to the \(x\)-axis in a plane are known as horizontal lines. Vertical Lines – Lines mapped from up to down or down to up and are parallel to the \(y\)-axis in a plane are known as vertical lines. Intersecting Lines – Whenever […]
