For points (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2), the gradient is [...]\text{[...]}[...].
For points (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2), the gradient is m=y2−y1x2−x1\boxed{m=\frac{y_2-y_1}{x_2-x_1}}m=x2−x1y2−y1.

A vertical line has an undefined gradient because its calculation requires division by zero.
1.2.3 Co-ordinate geometry in the x, y plane Flashcards
Flashcards for CCEA A Level Maths 1.2.3 Co-ordinate geometry in the x, y plane, covering the key formulae, methods and definitions you need to recall for AS 1, AS 2, A2 1 and A2 2. 22 cards, matched to the CCEA A Level Maths (2210) specification.
