Mrs. Abalone introduces the concept of constant rate of change, explaining how to find it using a formula. She provides a definition and demonstrates the process through four examples, each illustrating how to calculate the rate of change from a table. The lesson emphasizes the importance of the formula and offers practical tips for solving problems. The video concludes with a reminder to contact Mrs. Abalone for questions and an invitation to a Zoom meeting.
