The Distance and Midpoint Formulas

How far apart are the two points (7,0) and (14,0)? Without even drawing a graph, you might be able to say they are 7 units apart. They're both on the x axis, so it's just a straight line measurement. But how can you measure the distance between two random points on a graph?

The distance formula is an application of Pythagoras' theorem for right triangles.

"The distance of a point from the origin is equal to the square root of the sum of the squares of the coordinates."
