Mark scheme
Marking points from the official mark scheme (May/June 2014). The mark or mark type is shown in brackets.
- [B1] Mid-point (6, 5) co
- [B1] Gradient = – ½ co
- [B1] Perp gradient = 2 co
- [M1] Eqn y – 5 = 2(x – 6) Must be correct form of Perp
- [A1] Sets y to 0, → (3½, 0) co x = 3½ only is ok.
