An Odyssey Through Distance and Midpoint Formulas in the Plane
TL;DR: Drop two points on a coordinate plane and two questions usually follow — how far apart are they, and where is the spot exactly between them? For distance, you square the gap in x, square the gap in y, add them up, and take the square root. It is the Pythagorean theorem wearing coordinate […]
Mastering the Midpoint & Distance on the Number Line
Examples Practice Questions: Find the midpoint between the numbers \(2\) and \(8\) on the number line. Calculate the distance between the numbers \(-7\) and \(3\) on the number line. If the midpoint between two numbers \(a\) and \(b\) is \(5\), what is the value of \(b\) given \(a = 3\)? The midpoint is \(5\). The […]
