how to find distance formula with points. Let x 1y 1 be the point not on the line and let x 2y 2 be the point on the line. Note you could have just plugged the coordinates into the formula and arrived at the same solution.
Once youve done that just add the numbers that are under the radical sign and solve for d. Example 2 Find the distance between the two points 3 2 and 3 5. Distance Formula The Distance Formula squares the differences between the two x coordinates and two y coordinates then adds those squares and finally takes their square root to get the total distance along the diagonal line.
Look at the blue line going from 00 to 30.
Example 2 Find the distance between the two points 3 2 and 3 5. X 2 x 1 2 y 2 y 1 2. X 1 y 1. Know the distance formula.
