Write an equation perpendicular to

Perpendicular Line Calculator

We will use our previous knowledge of slopes and algebraic equations to learn about parallel and perpendicular lines in the coordinate plane. Thus, they are parallel lines. We now see that the two lines are parallel. We will also have to utilize what we know about equations in slope-intercept form.

In short, remember that perpendicular lines have opposite reciprocal slopes.

The reason for this is because the slope of a line is essentially the measure of an angle of a line from a perfectly horizontal line or the x-axis. For instance, consider the line If we want to find the equation of a line that is perpendicular to the given line we just need to follow two simple steps.

GO Parallel and Perpendicular Lines Now that we have a better understanding of lines and angleswe are ready to begin applying some of these concepts onto the Caresian coordinate plane.

Algebra Examples

Note that 2 is the x value of the ordered pair given. Math works just like anything else, if you want to get good at it, then you need to practice it.

This yields We can take a look at the graph of these lines to see that this line is indeed parallel to the given line and that it passes through 3, 1.

Now, we add y to both sides of the equation to get Subtracting 4x from both sides of the equation gives Now, if we look at both equations, we notice that they both have slopes of 2. Perpendicular lines are shown below. Note that -1 is the y value of the ordered pair given.

The equation of a line that is perpendicular to the x-axis and passes through the point (2, -1).

You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. While parallel lines have the same slope, lines that are perpendicular to each other have opposite reciprocal slopes.

How do we determine if these lines are parallel or if they intersect at some point? More specifically, the slope of a line is the measure of an angle of a line from a perfectly horizontal line or the x-axis.

Both sets of lines are important for many geometric proofs, so it is important to recognize them graphically and algebraically.

Write the equation using function notation. So, if we know the slope of the line parallel to our line, we have it made.

We need to do a little work in that department. Regardless of the magnitude of the new y-intercept, as long as the slope is identical, the two lines will be parallel. Recall that Tutorial Now we have So, we plug in the the x and y values of the point we were given to get We now plug in the m and b values we have found, so the equation of our line is We see that there does indeed exist a right angle at the intersection of the two lines in the figure shown below.

The Slope of a Line tells us that parallel lines have the same slope. Example 2 Find the equation of the line that passes through the point 8, 1 and is perpendicular to the line Similar to the Example 1, we first identify what the slope of our equation should be.

Now we can go on to the equation of our line: Parallel Lines Write the equation for the first line and identify the slope and y-intercept. If you said any point on the line and the slope, you are correct. What did you come up with?

Any line with a slope of 2 will be perpendicular to the given line. The graph of these equations is shown below. Example 1 Find the equation of a line that passes through the point 3, 1 and is parallel to the line In order to solve this kind of problem, we will need to keep in mind that parallel lines have the same slope.The calculator will find the equation of the parallel/perpendicular line to the given line, passing through the given point, with steps shown.
