D x 2 - x 1 2 y 2 - y 1 2 The expression x 2 - x 1 is read as the change in x and y 2 - y 1 is the change in y. To find the distance between two points x 1 y 1 and x 2 y 2 all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. Distance x 2 x 1 2 y 2 y 1 2.
Find the distance between 12 and -30 Find the distance using the Pythagorean Theorem.
312 922 3 - 1 2 9 - 2 2. 312 922 3 - 1 2 9 - 2 2. Youll use the following formula to determine the distance d or length of the line segment between the given coordinates. The expression above defines how to use the formula for the given two points.
