Graphing Linear Functions Using a Point and Slope

The video tutorial covers graphing lines using points and slope, starting with a bike race problem. It reviews function notation and the concept of slope as a rate of change. The tutorial demonstrates how to graph lines by using a point and slope, and applies these concepts to estimate travel time in a bike race scenario.

What does a negative slope indicate about the changes in y and x?

How do you graph a line using a point and a slope?

How long will it take to travel 50 miles at a rate of 15 miles per hour?
