Khan Academy: Identify Proportional Relationships From Graphs

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...

What proportion of learners will benefit from the lessons on proportional reasoning? Class members learn about proportional relationships, from unit rates to writing equations for proportional relationships. Then, they learn to use...

Practice telling whether or not the relationship between two quantities is proportional by analyzing word problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice writing proportional equations from tables.

Practice writing equations to describe proportional relationships. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Given the graph of a function, determine its domain or range. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Answer this question to see if understand how to determine a function based on a graph.

This video will give you examples of how to write equations in slope-intercept form. [11:10]

In this lesson, 7th graders will learn how to identify proportional relationships from tables, graphs, and equations. They will also learn how to identify the unit rate and write an equation to represent proportional relationships.

This video shows you how the change in y and the change in x are used to calculate the slope. [4:39]
