The rise is how much the y-coordinates changed, the run is how much the x-coordinates changed. Point-Slope Calculator Many functions to try! Do the arithmetic, and this will give you the value of b.

You have all the information you need to draw a single line on the map.

Slope-intercept form But, could we do better? It is simple to find a point because we just need ANY point on the line. The standard point slope formula looks like this: Hope that helps a bit! To get b, all you do is take your point and slope and use this equation: Finding the slope requires a little calculation, but it is also pretty easy.

Point-slope form looks like this: Putting it all together, our point is -1,0 and our slope is 2. 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.

In the example above, we took a given point and slope and made an equation. As you can see, point-slope form is nothing too complicated. Your point is -1,5. In this case it denotes a specific y value which you will plug into the equation. This is the equation of the line in a form called slope-intercept form.

While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler. That means that number will stay the same.Equation of a Line from 2 Points. Here are two points (you can drag them) and the equation of the line through them.

Explanations follow. The Points. Put the slope and one point into the "Point-Slope Formula" 3. Simplify; Step 1: Find the Slope (or Gradient) from 2 Points. 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 the example above, we took a given point and slope and made an equation. Now let's take an equation and find out the point and slope so we can graph it. Example 2. Find the equation (in point-slope form) for.

Let's quickly review the steps for writing an equation given two points: 1. Find the slope using the slope formula.

2. Find the y-intercept by substituting the slope and the coordinates of 1 point into the slope intercept formula, y = mx + b. 3. Write the equation using the slope and y-intercept. How to use point-slope form when you are given two sets of points?

Using point-slope form, find the equation of the following points: (2,3) and (5,1) Point-slope. Finding the Equation of a Line Given Two Points In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula Anytime we need to get the equation of a line, we need two things.

Slope-intercept equation from slope & point. Slope-intercept equation from two points. Practice: Slope-intercept from two points.

Slope-intercept form problems. Slope-intercept form review. Next tutorial. Point-slope form.
