Distance between 2 points
2. Prior learning
The distance between two points (x1,y1) and (x2,y2) is given by
d=√(x1−x2)2+(y1−y2)2📖
Midpoint of 2 points
2. Prior learning
The coordinates of the midpoint of two points is
(2x1+x2,2y1+y2)📖
Slope as rise over run
SL Core 2.1
The gradient of the line is a measure of its steepness. It is calculated by measuring the rise (change in y) in the line over a certain run (change in x).
The gradient of the line passing through the points (x1,y1) and (x2,y2) is
m=x2−x1y2−y1📖
