There are a few different ways to find the equation of line from 2 points. The equation of the line in the slope intercept form is y 11 2 x 2 5 5 0 5 x.
Just type numbers into the boxes below and the calculator which has its own page here will automatically calculate the equation of line in point slope and slope intercept forms.
How to get slope intercept form from 2 points. All you have to is give two points that the line goes through. Two point form formula. You can use the calculator below to find the equation of a line from any two points.
Remember we want we can find the equation y is equal to mx plus b. We need to find slope a and intercept b. It reads y mx b where m is the slope of the line and b is where it intercepts the y axis.
This will give you the value of m that you can plug into y mx b. So good place to start is we can find its slope. Although there are two standardized forms of writing out the equation for a line slope intercept form is usually the first method you learn.
For two known points we have two equations in respect to a and b let s subtract the first from the second. Let s assume it is a point with x 1 and y 1. The second step will be to find the y intercept.
Let s find slope intercept form of line equation from the two known points and. So let s find its equation. You need to follow the procedure outlined below.
The first step will be to use the points to find the slope of the line. Write down the coordinates of the first point. Slope intercept vs point slope form.
Where x1 x2 x axis points y1 y2 y axis points x 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. However if you are comfortable using the point slope form of a line then skip to the second part of this page because writing the equation from 2 points is easier with. This slope intercept form calculator allows you to find the equation of a line in the slope intercept form.
So the line will looks something like that. If you know two points on a line you can use them to write the equation of the line in slope intercept form. This is the slope intercept form where m is the slope and b is the y intercept.
I will draw a dotted line maybe easier do dotted line. The first half of this page will focus on writing the equation in slope intercept form like example 1 below.
