Write an equation of a line in point slope form

Note also that it is useful to pick a point on the axis, because one of the values will be zero. You could have used any triangle to figure out the slope and you would still get the same answer.

Example 1 You are given the point 4,3 and a slope of 2. Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. In this case it denotes a specific y value which you will plug into the equation.

As you can see, point-slope form is nothing too complicated. Therefore the slope of this line is 2. And of course, if you need more help, feel free to ask the volunteers on our math help message board.

Find the equation for this line in point slope form. Create the equation that describes this line in point-slope form. 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.

Try working it out on your own. The standard point slope formula looks like this: Finding the slope requires a little calculation, but it is also pretty easy. Your slope was given to you, so where you see m, use 2. The variable m is the slope of the line.

Example 2 Find the equation in point-slope form for the line shown in this graph: To write the equation, we need two things: Point-Slope Calculator Many functions to try!

Think about it this way: You have a starting point on a map, and you are given a direction to head. It is just one method to writing an equation for a line.

Just plug the given values into your point-slope formula above. We know how to use the point-slope form, so the final answer is: Your point is -1,5. Point-slope form is also used to take a graph and find the equation of that particular line. It is simple to find a point because we just need ANY point on the line.

You have all the information you need to draw a single line on the map. In the example above, we took a given point and slope and made an equation. Putting it all together, our point is -1,0 and our slope is 2.

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

The point slope form gets its name because it uses a single point on the graph and the slope of the line. Your final result should look like:Slope-intercept form is useful when we know the y- intercept of a line. However, we are not always given this information. When we know the slope and one point which is not the y-intercept, we can write the equation in point-slope form.

Point slop is one of the method used to find the straight line equation. Use the below point slope form calculator to calculate the equation of the straight line by entering the. You can find the straight-line equation using the point-slope form if they just give you a couple points: Find the equation of the line that passes through the points (–2, 4) and (1, 2).
