Enter a coordinate pair for each the starting and ending points according to the Cartesian coordinate system. Then click on Calculate. The calculator will determine the straight line distance between the two points as well as present the coordinates of each point as entered in the standard designation.
Point A is on the coordinate 4 and point B is on the coordinate -1. If we want to find the distance between two points in a coordinate plane we use a different formula that is based on the Pythagorean Theorem were (x 1 ,y 1) and (x 2 ,y 2) are the coordinates and d marks the distance:ethod 2: If we are working in a coordinate plane where the endpoints has the coordinates (x 1 ,y 1) and (x 2 ,y 2) then the midpoint coordinates is found by using the following formula: Video lesson: Find the midpoint of the line segment. 1  Pre-Algebra. 2  Algebra 1.
