Finding Slope from Points and Graphs

The video tutorial explains how to find slopes from graph points and tables. It introduces the concept of slope as a rate of change, recaps the slope formula, and demonstrates its application through multiple example problems. The tutorial emphasizes the importance of labeling points and writing the formula for accuracy. It concludes with a brief mention of using tables for slope calculations.

What is the definition of slope in terms of rate of change?

• Change in x over change in y

• Difference between x and y changes

• Sum of x and y changes

• Change in y over change in x
