Reduce Non-Linear Function to Linear Function - Examples (a) to (f)

Reduce each of the following equations to the linear form. Hence, state the gradient and the Y-intercept of the linear equations in terms of  a and b.
(a) y=a x 3 +b x 2
(b) y=ax+ b x
(c) y=axb x 2
(d) xy= p x +qx
(e) y=a x + b x
(f) a y = b x +1

[Note :
X and Y cannot have constant, but can have the variables (for example x and y)
 m and c can only have the constant(for example a and b), cannot have the variables x and y]
