Activity 9 and 10 Khan Academy Videos

*Use these videos to review for the test, to practice a concept you are usure about or to catch up if you’ve been absent!

(A master list of videos for the entire year is posted on my main page. These videos are for the currect Activity.

 

Activity 9

Rates of Change

9-1 Learning  Targets:

  • Determine the slope of a line from a graph.
  • Develop and use the formula for slope.

9-2 Learning  Targets:

  • Calculate and interpret the rate of change for a function.
  • Understand the connection between rate of change and slope.

9-3 Learning  Targets:

  • Show that a linear function has a constant rate of change.
  • Understand when the slope of a line is positive, negative, zero, or undefined.
  • Identify functions that do not have a constant rate of change and understand that these functions are not linear.

  • Write and graph direct variation.
  • Identify the constant of variation.

10-2 Learning Targets:

  • Write and graph indirect variations.
  • Distinguish between direct and indirect variation.
