I mean to say that u should plot a graph with this values

You've provided the values for the first data set. To plot the graphs and calculate the slopes, I will provide instructions for plotting and then calculate the slope for the first data set. For the second data set, please provide the complete list of values.

Graph 1: Data Set 1

Data Points (Current $I$ in A, Voltage $V$ in V):

• $(0.1953, 2.28)$
• $(0.1149, 2.45)$
• $(0.0812, 2.53)$
• $(0.0629, 2.58)$
• $(0.0515, 2.62)$
• $(0.0435, 2.65)$
• $(0.0377, 2.67)$
• $(0.0332, 2.68)$
• $(0.0297, 2.69)$
• $(0.0267, 2.70)$

Instructions for Plotting Graph 1:

1. Axes: Draw a horizontal axis (x-axis) for Current ($I$) in Amperes (A) and a vertical axis (y-axis) for Voltage ($V$) in Volts (V).
2. Scale:
   • For the x-axis (Current): Choose a scale that accommodates values from $0 \text{ A}$ to approximately $0.2 \text{ A}$. For example, $1 \text{ cm}$ could represent $0.02 \text{ A}$.
   • For the y-axis (Voltage): Choose a scale that accommodates values from approximately $2.2 \text{ V}$ to $2.7 \text{ V}$. For example, $1 \text{ cm}$ could represent $0.1 \text{ V}$.
3. Plot Points: Plot each $(I, V)$ pair from the data table on your graph paper.
4. Best-Fit Line: Draw a straight line that best fits the plotted points. This line should represent the general trend of the data.

Calculation of Slope ($\alpha_2$) for Graph 1:
We will use the first and last data points to calculate the slope.
Let $(I_1, V_1) = (0.1953 \text{ A}, 2.28 \text{ V})$ and $(I_2, V_2) = (0.0267 \text{ A}, 2.70 \text{ V})$.
The slope $\alpha_2$ is given by:

$$\alpha_2 = \frac{V_2 - V_1}{I_2 - I_1}$$ $$\alpha_2 = \frac{2.70 \text{ V} - 2.28 \text{ V}}{0.0267 \text{ A} - 0.1953 \text{ A}}$$ $$\alpha_2 = \frac{0.42 \text{ V}}{-0.1686 \text{ A}}$$ $$\alpha_2 \approx -2.491 \ \Omega$$

The slope for Data Set 1 is $\boxed{-2.491 \ \Omega}$.
