Explain how to write an equation in slope intercept form given two points

Writing linear equations using the slope-intercept form

We know how to use the point-slope form, so the final answer is: The standard point slope formula looks like this: As you can see, point-slope form is nothing too complicated. In the example above, we took a given point and slope and made an equation.

To write the equation, we need two things: Example 2 Find the equation in point-slope form for the line shown in this graph: Point-slope form is also used to take a graph and find the equation of that particular line. Create the equation that describes this line in point-slope form.

Think about it this way: Your slope was given to you, so where you see m, use 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.

You have a starting point on a map, and you are given a direction to head. You could have used any triangle to figure out the slope and you would still get the same answer.

Putting it all together, our point is -1,0 and our slope is 2. The point slope form gets its name because it uses a single point on the graph and the slope of the line.

Therefore the slope of this line is 2. In this case it denotes a specific y value which you will plug into the equation. 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.

It is just one method to writing an equation for a line. Example 1 You are given the point 4,3 and a slope of 2. Point-Slope Calculator Many functions to try! Just plug the given values into your point-slope formula above.

You have all the information you need to draw a single line on the map. The variable m is the slope of the line. Find the equation for this line in point slope form.

Using the Point-Slope Form of a Line

It is simple to find a point because we just need ANY point on the line. Finding the slope requires a little calculation, but it is also pretty easy.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. STEP 2: Now, use the point-slope formula with one of our points, (1, 3), and. Algebra > Lines > Finding the Equation of a Line Given Two Points. Page 2 of 2. Finding the Equation of a Line Given Two Points.

STEP 2: Now, use the. One type of linear equation is the point slope form, which gives the slope of a line and the coordinates of a point on it.

The point slope form of a linear equation is written as. In this equation, m is the slope and (x 1, y 1) are the coordinates of a point. To summarize how to write a linear equation using the slope-interception form you Identify the slope, m.

This can be done by calculating the slope between two known points of the line using the slope formula. 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 Algebra > Lines > Finding the Equation of a Line Given Two Points.
