Khan Academy: Comparing Linear Functions: Equations vs. Graph

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...

Introduce your algebra learners to linear and quadratic functions. Learners compare the differences and relate them back to the equations and graphs. Lead your class to discussions on the properties of a function or a constant slope...

Time to move on to nonlinear functions. Scholars create input/output tables and use these to graph simple nonlinear functions. They calculate rates of change to distinguish between linear and nonlinear functions.

This video explores a basic linear cost equation. Given a rate-per-photo and a one-time cost, write a function representing the amount a customer would pay for x number of photos.

In this video, we create an equation and graph to show a linear relationship based on the word problem. This is a good example for algebra and pre-algebra learners to help them understand creating equations and graphing relationships...

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]

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]

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...

This word problem is about two people who climb a wall. The formula is given for one and a table of values for the other and the problem asks who has the higher starting point, otherwise known as the initial value. [4:43]
