Introduction

Let’s say we want a program to perform some mathematical data manipulation on two-dimensional points. We may be interested in calculating values such as:

• The distance between 2 points.
• The midpoint of a segment, given 2 points.
• The equation of a line, given 2 points.
• The slope of a line.

To provide a concrete example, let’s write code to calculate the distance between 2 points. The distance between points $(x1, y1)$ and $(x2, y2)$ is $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$.
