Point Slope Form in Geometry

Blog Introduction: Point slope form is a way to write linear equations. It is especially useful when you are given a graph with two points. All you need to do is find the slope and then use the point and slope to write the equation. Keep reading to learn more!

What is point slope form?

Point slope form is a way of writing linear equations. The equation takes the form: y-y1=m(x-x1) y1 and x1 are coordinates of a point on the line m is the slope 

How do you find the equation in point slope form? 

There are a few steps involved in finding the equation in point slope form: 

First, you need to find the slope. You can do this by finding two points on the line and then using the formula m = (y2-y1)/(x2-x1). 

Once you have the slope, plug it into the equation above along with your coordinates for x1 and y1. 

You should now have your equation in point slope form! 

Why is point slope form useful? 

Point slope form is especially useful when you are given a graph with two points. All you need to do is find the slope and then use the point and slope to write the equation. This can be much easier than trying to find the equation by looking at the graph alone. 

Conclusion: 

Point slope form is a helpful way to write linear equations, especially when you are given a graph with two points. To find the equation in point slope form, simply calculate the slope using two points on the line and then plug that value into the equation along with your x1 and y1 coordinates. Point slope form can be very helpful when trying to determine an equation from a graph alone.
