Best ResponseYou've already chosen the best response.0There is a distance formula to find the distance between any two points on the coordinate plane, but if the points are on a horizontal line or on a vertical line, you don't need to use the formula, and you can still find the distance easily.

Best ResponseYou've already chosen the best response.0See? The points are on a horizontal line, so the distance is simply the distance along the horizontal line the points lie in.

Best ResponseYou've already chosen the best response.0@pooja195 wrote the distance formula. If the points do not lie on a horizontal or vertical line, you need to use it. If the points do lie on a horizontal or vertical line, you can still use it, but my way above is shorter.
