The first step is to find the slope of the line that goes through those two points. Find the equation of a line that passes through the point 5, 5 and is parallel to What is your answer? Find the equation of the line that goes through the point 4, 5 and has a slope of 2.

Two of those are: The process for obtaining the slope-intercept form and the general form are both shown below. You would first find the slope of the given line, but you would then use the negative reciprocal in the point-slope form.

That is because the point-slope form is only used as a tool in finding an equation. We know we are looking for a line parallel to. If we re-write in slope-intercept form, we will easily be able to find the slope.

Now you need to simplify this expression. The strategy you use to solve the problem depends on the type of information you are given. Since you have a point and a slope, you should use the point-slope form of a line.

When using this form you will substitute numerical values for x1, y1 and m. Transforming the slope-intercept form into general form gives Parallel and Perpendicular There is one other common type of problem that asks you to write the equation of a line given certain information.

Both forms involve strategies used in solving linear equations.

You may be wondering why this form of a line was not mentioned at the beginning of the lesson with the other two forms. Find the equation of the line that passes through the points -2, 3 and 1, Now simplify this expression into the form you need.

Look at the slope-intercept and general forms of lines. If you need help rewriting the equation, click here for practice link to linear equations slope.

Given a Point and a Slope When you are given a point and a slope and asked to write the equation of the line that passes through the point with the given slope, you have to use what is called the point-slope form of a line.

You can take the slope-intercept form and change it to general form in the following way. As we have in each of the other examples, we can use the point-slope form of a line to find our equation. We are given the point, but we have to do a little work to find the slope.

How is this possible if for the point-slope form you must have a point and a slope? Given Two Points When you are given two points, it is still possible to use the point-slope form of a line.

When a problem asks you to write the equation of a line, you will be given certain information to help you write the equation. You can use either of the two points you have been given and you equation will still come out the same.

The process for simplifying depends on how you are going to give your answer. Transforming the slope-intercept form into general form gives If the problem in Example 4 had asked you to write the equation of a line perpendicular to the one given, you would begin the problem the same way. Find the equation of the line that passes through 1, -5 and is parallel to.

You also have TWO points use can use. That means our line will have the same slope as the line we are given. If you are comfortable with plugging values into the equation, you may not need to include this labeling step.

This type of problem involves writing equations of parallel or perpendicular lines. You will NOT substitute values for x and y.Writing Equations of Lines: Equations of lines come in several different forms. Two of those are: slope-intercept form; where m is When a problem asks you to write the equation of a line, you will be given certain information to help you write the equation.

The strategy you use to solve the problem depends on the type of information you are. Each one expresses the equation of a line, and each one has its own pros and cons. For instance, point slope form makes it easy to find the line's equation when you only know.

Find the equation, in standard form of the line perpendicular to 2x-3y=-5 and passing through (3,-2) Write the equation in standard form with all integer coefficient. Hi Kristy. I can show you how it's done with a similar problem, then you can follow those steps in solving your question.

The Standard Form of the equation of a line looks like: Ax + By = C [ note: the slope is (-A/B) ] First, convert the given equation into Standard Form.

Write an equation in slope -intercept form for the line described. slopepasses through (0, 5) 62/87,21 Substitute m = and (x, y) = (0, 5) in the equation y.

Start studying Linear equations. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Write the equation of the line containing the point (15,5) with a slope of 2/3. standard form of a linear equation.

Ax + By = C, where A,B, and C are integers, A is positive and A and B are not both zero.
