To find the equation of the line of best fit for the data in your table, you would typically input the data points into the Desmos graphing calculator and then use its regression feature to find the best-fit line. However, since I can't access external sites, I can guide you through the process:
1. **Open Desmos**: Go to the Desmos graphing calculator website.
2. **Enter Your Data**: Input your data points in a list format. For example, if your data points are (x1, y1), (x2, y2), ... etc., enter them in the format:
```
A = {(x1, y1), (x2, y2), (x3, y3), ...}
```
3. **Use Regression to Find Best Fit Line**: After you have entered your points, type the following to perform linear regression:
```
L_1 = A
L_2 = a x + b
```
Then use the regression command:
```
(a, b) = regress(L_1, L_2)
```
4. **View the Result**: The output will provide you with the values of a (slope) and b (y-intercept), which you can then form into the equation of the line in the format \( y = ax + b \).
5. **Compare with Proposed Equations**: Once you obtain the line of best fit, compare it with the given equations:
- \( y = 3.24x + 12.68 \)
- \( y = 5.27x + 10.23 \)
- \( y = 2.61x + 12.74 \)
Without the specific data points from your table, I cannot give a definite answer. However, following these steps on Desmos will yield the correct equation of the line of best fit based on your actual data. If you have specific numerical data, feel free to share it here, and I can help you calculate the line of best fit.
