Determining Negative Slope from a Table of Values

The video tutorial explains how to calculate the slope of a line using a table of values. It emphasizes that the values do not need to be consecutive and demonstrates the process of selecting two points to find the change in y-coordinates over the change in x-coordinates. The tutorial provides a detailed example calculation, highlighting the importance of understanding the difference between values to determine the slope, which is -2 in the given example.

What is the main concept introduced in the beginning of the video?

• Finding the y-intercept

• Calculating the slope

• Solving quadratic equations

• Determining the x-intercept
