Finding the rate of change from a graph

The video tutorial explains how to find the rate of change from a graph, focusing on linear graphs. It introduces the concept of slope as the rate of change between two quantities, typically represented as the change in y-values over the change in x-values. The tutorial provides a detailed example of calculating slope using two points and explains the importance of understanding change through subtraction. It also discusses different methods to interpret slope from a graph, emphasizing that the direction of reading the graph (left to right or right to left) affects the sign of the slope but not its magnitude.

What is the general formula for slope?

Describe the difference between calculating slope from left to right versus right to left.
