Understanding Slope and Coordinate Pairs

This lesson introduces the concept of slope, defined as the change in Y over the change in X. Using coordinate pairs (6, 3) and (-3, 6), the lesson demonstrates how to calculate the slope by finding the change in Y and X, simplifying the expression, and arriving at the final slope of -1/3. The lesson emphasizes understanding the process of calculating slope through subtraction and simplification.
