The relationships between slopes of parallel and perpendicular lines can be used to write equations of parallel and perpendicular lines.Let’s start with an example involving parallel lines.Example Write the equation of a line that is parallel to the line x–y=5x–y=5 and goes through the ...
Parallel lines are straight lines that extend to infinity without touching at any point. Perpendicular lines cross each other at a 90-degree angle. Both sets of lines are important for many geometric proofs, so it is important to recognize them graphically and algebraically. You must know the s...
Writing Equations of Parallel LinesIf we know the equation of a line, we can use what we know about slope to write the equation of a line that is either parallel or perpendicular to the given line.Suppose we are given the following function:...
