SPM Practice 2 (Question 4 & 5) - SPM Additional Mathematics

Question 4:
The diagram shows part of the straight line graph obtained by plotting $\frac{y}{x}$ $\frac{y}{x}$ against $\sqrt{x}$ $\sqrt{x}$ .

Given its original non-linear equation is $y = p x + q x^{\frac{3}{2}}$ $y = p x + q x^{\frac{3}{2}}$ . Calculate the values of p and q.

Solution:

Question 5:
The diagram below shows the graph of the straight line that is related by the equation $\frac{x}{y} = \frac{2}{x} + 3 x$ $\frac{x}{y} = \frac{2}{x} + 3 x$ .

Find the values of p and k.
