In the examples worked in this lesson, answers will be given in both forms. Find the equation of a line that passes through the point 5, 5 and is parallel to What is your answer?

That means our line will have the same slope as the line we are given.

Putting it all together, our point is -1,0 and our slope is 2. Given Two Points When you are given two points, it Write equations in slope intercept form still possible to use the point-slope form of a line.

The rate is your slope in the problem. What will we look for in the problem? To learn more about parallel and perpendicular lines and their slopes, click here link to coord geometry parallel As a quick reminder, two lines that are parallel will have the same slope.

Using the Point-Slope Form of a Line Another way to express the equation of a straight line Point-slope refers to a method for graphing a linear equation on an x-y axis.

Find the equation of the line that passes through 1, -5 and is parallel to. The process for obtaining the slope-intercept form and the general form are both shown below.

The process for simplifying depends on how you are going to give your answer. We know we are looking for a line parallel to. In this case it denotes a specific y value which you will plug into the equation.

While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler. If you are comfortable with plugging values into the equation, you may not need to include this labeling step. Your final result should look like: The variables x and y should always remain variables when writing a linear equation.

In the example above, you were given the slope and y-intercept. As you can see, point-slope form is nothing too complicated. What is your answer?

All you need to know is the slope rate and the y-intercept. Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph.

Just plug the given values into your point-slope formula above. Your point is -1,5. Note also that it is useful to pick a point on the axis, because one of the values will be zero. Write the equation of the line that passes through the points 7, -3 and 7, 0.

The strategy you use to solve the problem depends on the type of information you are given. The variable m is the slope of the line.

The first step is to find the slope of the line that goes through those two points. As we have in each of the other examples, we can use the point-slope form of a line to find our equation.

Find the equation of the line that goes through the point 4, 5 and has a slope of 2. Although the numbers are not as easy to work with as the last example, the process is still the same. Equations of lines come in several different forms.

If you need to practice these strategies, click here. Example 2 Find the equation in point-slope form for the line shown in this graph: Find the equation of the line that passes through 0, -3 and -2, 5.

Point-slope form is also used to take a graph and find the equation of that particular line. Plug those values into the point-slope form of the line: Example 1 You are given the point 4,3 and a slope of 2.y-intercept = −4 V.

Write the standard form of the equation of the line through the given point with the given slope. 31) through: (−4, 4), slope = − 7 4 32) through: (1, 2), slope = 6 X. Write the standard form of the equation of the line through the given points. Jul 18, · Slope intercept form is a common way to represent a linear equation.

Slope intercept form is written in the form of "y = mx + b" -- where the letters are to be filled in or solved, such as: "x" and "y" values represent the "x" and "y".

Writing Linear Equations Date_____ Period____ Write the slope-intercept form of the equation of each line. 1) 3 x − 2y = −16 2) 13 x − 11 y = −12 3) 9x Write the point-slope form of the equation of the line described. 17) through: (4, 2), parallel to y. Write the equation in slope-intercept form.

Write an equation of the line that passes through each pair of points. (9, í2), (4, 3) 62/87,21 Find the slope of the line containing the given points. Use the slope and either of the two points to find the y-intercept. The slope intercept form equation is expressed as y = mx + c, where 'm' represents the slope of the line and 'c' represents the y-intercept of a line.

You can find the equation of a straight line based on the slope and y-intercept using this slope intercept form calculator. Slope Intercept Form.
