Finding Slope from a Table: Key Concepts and Applications

The video tutorial explains how to find the slope of a function given as a table. It begins by introducing the slope formula and the need for two ordered pairs. The instructor demonstrates how to select and label these pairs from the table. The values are then substituted into the slope formula to calculate the slope. Finally, the slope is verified by observing the consistent change in Y values as X values increase by one.

What is the formula for finding the slope of a function?

• x2 - x1 over y2 - y1

• y2 + y1 over x2 + x1

• y1 - y2 over x1 - x2

• y2 - y1 over x2 - x1

What does the slope of 9 indicate about the change in y-values?

• Y decreases by 9 for every increase in X by 1
