Khan Academy: Comparing Linear Functions Word Problem: Climb

How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

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...

In this video, Sal solves a word problem sent in by a listener with two cyclists riding towards each other over a given time. It is an interesting problem regarding ratios and the relationship between distance, rate, and time. He shows...

A few word problems involving age are presented. Starting with a simple problem and progressing to more complicated word problems, Sal uses a chart to organize the information given in the more complicated problem to solve for the variable.

For most people, solving word problems takes a lot of work. But Sal makes it look simple! Follow along as he unpacks this complicated word problem. He even demonstrates how to answer. Excellent!

Here are some more age word problems. The instructor uses a chart again to organize the information given. He works through the problem but ends the video with a solution that appears erroneous but is correct. The answer seems too large...

This presentation demonstrates how to solve an age word problem. It is worth the time it takes to view it.

Video lecture examines how to compare linear functions given a table of values and four linear graphs. How do you determine which graph increases faster than the function represented in the table? [3:39]

Compares the equation of one linear function with the graph of another to determine which of the given statements about them are true. [2:22]

Given a table of values for a linear function, see how to determine which of four linear graphs represents the same rate of change. [2:35]
