Step-by-step explanation:
You know that the distance AB between two points in a plane with Cartesian coordinates A(x1,y1) and B(x2,y2) is given by the following formula:
AB = √(x2−x1)2+(y2−y1)^2

The distance formula is really just the Pythagorean Theorem in disguise. To calculate the distance AB between point A(x1,y1) and B(x2,y2) , first draw a right triangle which has the segment ¯AB as its hypotenuse. Since AC is a horizontal distance, it is just the difference between the x -coordinates: |(x2−x1)| .
