It's going to be equal to negative four. We know we are looking for a line parallel to. And no matter where you are on your mathematical journey, the idea that Algebra and Calculus are intrinsically connected is just plain cool!
Think about it this way: Your point is -1,5. Find the equation of the line that passes through the points -2, 3 and 1, I substituted the value for the slope -2 for m and the value for the y-intercept 5 for b. That's our change in Y. Writing an Equation Given the Slope and Y-Intercept Write the equation for a line that has a slope of -2 and y-intercept of 5.
Passes through 2, 3 and parallel to. It is just one method to writing an equation for a line. As you can see, point-slope form is nothing too complicated.
You would first find the slope of the given line, but you would then use the negative reciprocal in the point-slope form. How do we write an equation for a real world problem in slope intercept form? And through this lesson, we will discover that the point-slope form definition is really just an extension of our beloved slope formula.
Let's first quickly review slope intercept form. You will NOT substitute values for x and y. The point slope form gets its name because it uses a single point on the graph and the slope of the line. And I encourage you, like always, pause the video and see if you can do it. And point-slope form is very easy to generate if you know a point on the line, or if you know a point that satisfies, where the X and Y coordinates satisfy the linear equation, and if you were to know the slope of the line that represents the solution set of that linear equation.
Or read more lessons on slope intercept from other websites. Since you have a point and a slope, you should use the point-slope form of a line. Write the equation using function notation. The constant 'm' is the slope of the graph -- notice how it multiplies your x term. We've gone down eight.
In fact, this method is so straightforward, that you will find writing linear equations super easy!Point-slope form.

Represent equations from point slope form to standard form. Write equations of parallel lines and perpendicular lines by finding the line that passes through a point and has either parallel slope or perpendicular slope to the graph of a.
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 lietuvosstumbrai.com graphing a linear equation, the whole idea is to take pairs of x's and y's and plot them on the graph.
