Finding Slope and y-Intercept from Graphs

The video tutorial explains the concepts of slope and y-intercept using graphs. It defines slope as the rate of change and rise over run, and demonstrates how to identify points on a graph to calculate slope. The tutorial also covers how to find the y-intercept by locating where the line crosses the y-axis. The video provides step-by-step instructions for calculating slope and y-intercept, emphasizing the importance of understanding these concepts in graph analysis.
