Coordinate Geometry & Vectors
Gradient, distance, midpoint and the equation of a line in coordinate geometry, plus vectors in 2D column form.
What this topic covers
- Gradient measures how steep a line is
- Distance between two points uses Pythagoras' theorem
- The midpoint is the average of the coordinates
- The equation of a line is y = mx + c
- A vector in column form has a magnitude
- Vectors add, subtract, and scale component by component
