Final answer:
To find the equation of a line passing through two points using a calculator, enter the data into a calculator and make a scatter plot. Then, use the calculator's regression function to find the equation of the least-squares regression line.
Step-by-step explanation:
To find the equation of a line passing through two points using a calculator, follow these steps:
1. Enter the data into a calculator and make a scatter plot.
2. Use the calculator's regression function to find the equation of the least-squares regression line. Add this to your scatter plot from Part A.
For more accurate results, it is recommended to choose two points on the line that are far apart.
