They see that just as points on the line can be located by their distance from 0, the plane’s coordinate system can be used to locate and plot points using two coordinates. They then use the coordinate system to explore relationships between points, ordered pairs, patterns, lines and, more abstractly, the rules that generate them.
Solution: Use the coordinates of the endpoints of the line segment as ( x,y ) and ( 0, 0 ) Using distance formula we have, d= $\sqrt { (x -0)^2+ (y-0)^2}$. d= $\sqrt {x^2+y^2}$. Therefore, d=$\sqrt {x^2+y^2}$ is the formula for the distance between the origin and a point on a rectangular coordinate system.
Rules. How to find the distance between two points? 1. Substitute the x- and y-coordinates into the distance formula. 2. Solve using order of operations. Example. Use the distance formula to find the distance between two points X (-7, 5) and Y (2, -6). Round the answer to the nearest tenth. Solution.

What Is the Distance between Two Points? There is only one line passing through two points. So, the distance between two points can be calculated by finding the length of the line segment connecting the two points. For example, if P and Q are two points and PQ $= 8$ feet, it means that the distance between the points P and Q is 8 feet.
