Question

Variables $x$ and $y$ are related in such a way such that, when $xy$ is plotted against $x^2$, a straight line is produced. The line passes through the points $A(1, 9)$, $B(5, 1)$ and $P(4, p)$ as shown in the diagram. Find $p$. Express $y$ in terms of $x$.

Accepted Answer

(a) $p=3$ (b) $\displaystyle y=\frac{11-2x^2}{x}$
