| Difficulty | Standard +0.3 This is a straightforward hyperbola question requiring identification of an x-intercept (trivial substitution y=0) and finding a point on the curve given a gradient constraint. Part (b) involves simultaneous equations with a linear equation and the hyperbola equation, which is standard FP1 technique with no novel insight required. Slightly easier than average due to the direct nature of both parts. |

8 The diagram shows a part of the curve
$$\frac { x ^ { 2 } } { 4 } - \frac { y ^ { 2 } } { 6 } = 1$$
and a chord $P Q$ of the curve, where $P$ lies on the $x$-axis.\\
