Understanding Graph Intercepts and Ordered Pairs

The video tutorial explains how to analyze a graph showing Sally's distance from home over 22 minutes. It covers the interpretation of vertical and horizontal intercepts and the significance of ordered pairs. The vertical intercept indicates Sally starts 11 miles from home, while the horizontal intercept shows she arrives home after 22 minutes. The ordered pair (6, 8) signifies that after 6 minutes, Sally is 8 miles from home.

What does the graph represent in the context of Sally's journey?

• Sally's travel expenses

• Sally's distance from home over time

• Sally's speed over time

• Sally's favorite places
