14. MP Reason If you know one point on the graph of a line, what other piece of information do you need in order to construct the function representing that line in the form \( y=m x+b \) ? Explain.

2imalify \( \frac{x^{2}-y^{2}}{x^{2} x y} \) \( \frac{y+2 x-3 y}{3 x-2 y}=4 \), evaluate \( 2 x y \) If \( z=\sqrt{x^{2}-y^{2}} \), express \( x \) interm 9 \( y \) and 2

Question 8 ( 3 marks) What is the equation of the line that passes through the points \( (1,6) \) and \( (3,2) \) ? \( y=\square x+\square \)

2.3 Express \( \frac{1}{\sqrt{2}+1} \) in its simpl

ii) \( \frac{4 x^{2}+3 x+7}{x+1} \)

d the exact value of the solution to the equation \( 2 e^{2 x}-7 e^{x}-4=0 \)
