| Topic | Straight Lines & Coordinate Geometry |
| Type | Line intersections with axes |
| Difficulty | Easy -1.2 This is a straightforward coordinate geometry question requiring basic algebraic manipulation. Part (i) involves substituting y=0 into a linear equation (routine procedure), and part (ii) requires solving simultaneous equations by substitution (standard technique with minimal steps). Both parts are simpler than typical A-level questions as they test only fundamental skills without any problem-solving or geometric insight. |

3 (i) Find the coordinates of the point where the line $5 x + 2 y = 20$ intersects the $x$-axis.\\
(ii) Find the coordinates of the point of intersection of the lines $5 x + 2 y = 20$ and $y = 5 - x$.
