Enter the slope of a line, constant b, and either the x or y coordinate at the end point. The endpoint calculator will display the missing coordinate value for the end point.
The following formula is used to calculate an endpoint of a line.
Y = kx+b
- Where X and Y are coordinate points
- X is the slope
- b is a constant
In this case, the formula above is actually the point slope form of a line. In order to calculate the end point of a line of this form, you only need to know either the x or y coordinate of the end point and the formula can solve for the other coordinate.
How to calculate an endpoint
- First, determine the slope of a line
Using the information given, or using two different points, calculate the slope of the line. You can also use this slope calculator to help.
- Next, determine the constant b
Using the same points as used in step 1, calculate the constant b.
- Finally, Calculate the missing variable
Using the information from steps 1 and 2, along with either the x or y point of the end point, calculate the other coordinate point of the endpoint.
An endpoint of a line is a theoretical point in which the line ceases to exist after that point. Most times lines are expressed at infinite, but when talking in terms of finite distances a line can in fact have an endpoint.
The end point is determined using an equation for a line and a coordinate point along that line. After that coordinate point the line no longer continues on.
