| Topic | Straight Lines & Coordinate Geometry |
| Type | Line intersections with axes |
| Difficulty | Easy -1.2 This is a straightforward C1 question testing basic coordinate geometry. Finding axis intercepts requires simple substitution (set x=0, then y=0), and finding the gradient involves rearranging to y=mx+c form or using -A/B from the general form. Both are routine procedures with no problem-solving required, making this easier than average. |

Question 2:
2 | (i) (0, 4) and (6, 0)
(ii) −4/6 o.e. or ft their (i) isw | 2
2 | 1 each; allow x = 0, y = 4 etc; condone
x = 6, y = 4 isw but 0 for (6, 4) with no
working
1 for −4 x or 4/−6 or 4/6 o.e. or ft
6
(accept 0.67 or better)
0 for just rearranging to y =−2 x+4
