Khan Academy: Algebra I Worked Examples: Basic Linear Function

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Find a linear function that represents a real-world relationship that is given verbally. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Is it possible to tell if a table of values represents a linear function or a nonlinear function? One way is to graph the ordered pairs to see if it makes a straight line. But, take a look at the rate of change in the table. If the rate...
