| Topic | Straight Lines & Coordinate Geometry |
| Type | Equation of line through two points |
| Difficulty | Easy -1.2 This is a straightforward application of finding gradient from two points (m = (y₂-y₁)/(x₂-x₁) = 20/4 = 5) then using y - y₁ = m(x - x₁) to find c. It's a standard C1 textbook exercise requiring only routine calculation with no problem-solving or conceptual challenge, making it easier than average. |
| Spec | 1.03a Straight lines: equation forms y=mx+c, ax+by+c=0 |
2 Find the equation of the line passing through $( - 1 , - 9 )$ and $( 3,11 )$. Give your answer in the form $y = m x + c$.
