Slope Calculation Using TI-83 Calculator

The video tutorial demonstrates how to calculate the slope of a line passing through two points using a TI-83 calculator. It provides two examples: one with points (5, 7) and (4, -2), and another with points (-6, 2) and (-7, -3). The process involves entering the points into the calculator, using the linear regression function to find the slope, and interpreting the results.

What is the first step in finding the slope using the TI-83 calculator?

• Reset the calculator

• Go to the graphing menu

• Turn on the calculator

• Enter the points into the calculator
