Calculating Slope and Initial Values

The video tutorial covers writing linear equations from real-life situations and graphs. It includes examples such as a video club membership, a coffee cafe gift card, office space rent, and Harry's weekly allowance. Each example demonstrates how to identify the slope and y-intercept to form equations in slope-intercept form.
