You could have used any triangle to figure out the slope and you would still get the same answer.

Point-slope form is also used to take a graph and find the equation of that particular line. We know how to use the point-slope form, so the final answer is: In the example above, we took a given point and slope and made an equation.

The standard point slope formula looks like this: Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. It is simple to find a point because we just need ANY point on the line. 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.

Think about it this way: Note also that it is useful to pick a point on the axis, because one of the values will be zero.

It is just one method to writing an equation for a line. Create the equation that describes this line in point-slope form. Find the equation for this line in point slope form.

Therefore the slope of this line is 2. Your slope was given to you, so where you see m, use 2. Try working it out on your own. Example 2 Find the equation in point-slope form for the line shown in this graph: Point-Slope Calculator Many functions to try!

In this case it denotes a specific y value which you will plug into the equation. Your point is -1,5. And of course, if you need more help, feel free to ask the volunteers on our math help message board.

While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler. Example 1 You are given the point 4,3 and a slope of 2. Just plug the given values into your point-slope formula above.

As you can see, point-slope form is nothing too complicated. To write the equation, we need two things: You have all the information you need to draw a single line on the map. You have a starting point on a map, and you are given a direction to head.

The variable m is the slope of the line. Putting it all together, our point is -1,0 and our slope is 2. Your final result should look like: The point slope form gets its name because it uses a single point on the graph and the slope of the line.

Finding the slope requires a little calculation, but it is also pretty easy.Review point-slope form and how to use it to solve problems.

use to find the equation of a line: It's called the point-slope formula (Duh!) You are going to use this a LOT! Luckily, it's pretty easy -- let's just do one. You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line).

It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis. 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.

Point-slope form is y - y_1 = m (x - x_1) where x_1 and y_1 are the given coordinates and m is the slope. When you plug the given values into the equation you get y - 3 = 6 (x - 8)/5(9). 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 .
