Length from Coordinates

Length from Coordinates
Introduction

When two points are plotted on a coordinate plane, the distance between them can be calculated using their coordinates. Finding this length is an important skill that connects arithmetic, absolu...

Let's find the distance between your house and your school on a grid map.

Suppose your house is at point A with coordinates (2, 1) and your school is at point B with coordinates (2, 6).

Notice that the x-coordinates are the same, so the points line up vertically. To find the distance, you only look at the change in the y-values, whi...
