CAIE: O Level - Mathematics D 4024 - Paper 2

Graphs / Coordinate Geometry

KEYPOINTS:

Mid Point = \(\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right)\)
Gradient = \( \frac{y_2 - y_1}{x_2 - x_1}\)
Distance = \(\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\)
Two straight lines are Parallel if their Gradients are same
Two straight lines are Perpendicular if the product of their gradient is –1

EQUATION OF LINE

y = mx + c
y – y₁ = m(x – x₁)
ax + by + c = 0
