| Topic | Straight Lines & Coordinate Geometry |
| Type | Equation of line through two points |
| Difficulty | Easy -1.2 This is a straightforward application of finding the equation of a line through two points using the gradient formula m = (y₂-y₁)/(x₂-x₁) followed by y - y₁ = m(x - x₁). It's a routine AS-level question requiring only basic recall and simple arithmetic, making it easier than average. |
