And of course, if you need more help, feel free to ask the volunteers on our math help message board. It is just one method to writing an equation for a line.

Putting it all together, our point is -1,0 and our slope is 2. Think about it this way: It is simple to find a point because we just need ANY point on the line. Point-Slope Calculator Many functions to try! Try working it out on your own.

Example 1 You are given the point 4,3 and a slope of 2.

You have all the information you need to draw a single line on the map. We know how to use the point-slope form, so the final answer is: Point-slope form is also used to take a graph and find the equation of that particular line. Your point is -1,5. The point slope form gets its name because it uses a single point on the graph and the slope of the line.

You have a starting point on a map, and you are given a direction to head. Find the equation for this line in point slope form. Therefore the slope of this line is 2. Finding the slope requires a little calculation, but it is also pretty easy. You could have used any triangle to figure out the slope and you would still get the same answer.

In the example above, we took a given point and slope and made an equation. Your slope was given to you, so where you see m, use 2. As you can see, point-slope form is nothing too complicated. Example 2 Find the equation in point-slope form for the line shown in this graph: The standard point slope formula looks like this: In this case it denotes a specific y value which you will plug into the equation.

Note also that it is useful to pick a point on the axis, because one of the values will be zero. Create the equation that describes this line in point-slope form.

While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler. The variable m is the slope of the line.

To write the equation, we need two things: Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. 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.

Just plug the given values into your point-slope formula above. Your final result should look like:The equation is useful when we know: one point on the line ; and the slope of the line, ; and want to find other points on the line. Let's find how.

What does it stand for? (x 1, y 1) is a known point. m is the slope of the line (x, y) is any other point on the line.

Example 1: Write an equation of the following line in point-slope form: Graph of a Line First, find the slope using the points (- 2, 3) and (3, - 1): m = = =.

Aug 29, · To find the equation of a line when you are given a point and the slope, use the equation b = y - mx. In this equation, b is the y-intercept, y is the y-coordinate of the point, x is the x-coordinate of the point, and m is the slope%(23).

Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form method.

Point slope method is one such method used to find the straight line equation when one co-ordinate and slope is given. 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.

When graphing a linear equation, the whole idea is to take pairs of x's and y's and plot them on the graph. Find the equation of the line that passes through the point (-2, 6) with a slope of 3.
