Parallel and Perpendicular Line Calculator - eMathHelp.
Find the Parallel Line, Use the slope-intercept form to find the. -intercept form is, where is the slope and is the y-intercept. Using the slope-intercept form, the slope is. To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula. Use the slope and a given point to substitute for and in the point-slope form, which is derived.
How Do You Write an Equation of a Line in Slope-Intercept Form If You Have One Point and a Parallel Line? Want to find the slope-intercept form of a line when you're given a point on that line and another line parallel to that line? Remember, parallel lines have the same slope. If you can find the slope of that parallel line, you'll have the.
This videos explains how one can easily find the parallel line to a given mathematical equation. He starts by explaining what it means for two lines to be parallel mathematically speaking. Defining two lines, then comparing the slope of both lines you can mathematically determine that they are in fact parallel. He then moves to common math problems found on tests where you are given a point.

Last week we worked on writing the equation of the line using the slope and either the y-intercept or a set of points on the line. Today we are going to extend our knowledge by looking at how knowing when lines are parallel can help us write an equation. Let’s take a look at the graph of two lines and see what we notice about their graphs and their equations.
Explanation:. Converting the given line to slope-intercept form we get the following equation: For parallel lines, the slopes must be equal, so the slope of the new line must also be.
To write the equation of a line parallel or perpendicular to another line, we follow the same principles as we do for finding the equation of any line. After finding the slope, use the point-slope formula to write the equation of the new line. How To: Given an equation for a line, write the equation of a line parallel or perpendicular to it. Find the slope of the given line. The easiest way to.
