Linearize the equation P = V2 / (R+A) to plot a graph.

a) To plot a suitable graph, we need to linearize the given equation $P = \frac{V^2}{R+A}$.

Step 1: Rearrange the equation.

$$P = \frac{V^2}{R+A}$$

Invert both sides:

$$\frac{1}{P} = \frac{R+A}{V^2}$$

Separate the terms:

$$\frac{1}{P} = \frac{R}{V^2} + \frac{A}{V^2}$$

This equation is in the form of a straight line $y = mx + c$, where:
$y = \frac{1}{P}$
$x =
