How to find the distance between two points on a graph. In this lesson you will learn to use absolute value to find distances between points with the same x and y value by using a coordinate plane. In the equation above y2 - y1 Dy or vertical change while x2 - x1 Dx or horizontal change as shown in the graph provided.
D x 2 x 1 2 y 2 y 1 2 z 2 z 1 2.
In this lesson you will learn to use absolute value to find distances between points with the same x and y value by using a coordinate plane. The linear distance between the two points is the square root of the sum of the squared values of the x-axis distance and the y-axis distance. 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. The coordinates of the two points in the graph is.
