Linear Functions Teacher Resources

In this task, students are shown a table of U.S. population data between 1982 and 1988 and are asked to explore whether linear functions would be appropriate to model relationships within the data. Aligns with F-LE.B.5 and F-LE.A.1.b.

In this task, young scholars prove that linear functions grow by equal differences over equal intervals, and notice that in this case, the equal differences have the same value as the slope. Aligns with F-LE.A.1.a.

This video demonstrates how to determine if a function is linear or not based on a table of x and y values. It also demonstrates how to graph the values in order to check if the function is linear or not. [4:01]

This resource presents a complete and detailed look at linear regression. This guide provides lots of details and graphs to explain each concept.

[Free Registration/Login may be required to access all resource tools.] Students learn to use function notation to graph functions. Students examine guided notes, review guided practice, study vocabulary, watch instructional videos and...

Students will compare functions by graphing the functions and describing the patterns in the graphs.

Students investigate linear relationships. The resource includes the activity and instructor resources.

Students learn to develop the equation of a line from its graph. They also learn to write the equation of a line from the slope and the y-intercept, a point and the slope, and two points. They also investigate slopes of lines that are...

A video showing which of the graphs represents the solutions to the given systems of equations. [1:27]

Students watch a detailed example that examines if a set of data is linear. A video tutorial examines the algebra concept.

Given a function find out which other functions are increasing at the same rate as the given function.

A video demonstration on how to find the solution of two systems of equations.

Students learn to associate the slope of a straight line with a constant rate of change. They also learn to calculate the rate of change from data points on a line, using the correct units. Students also learn to read from a linear...

Students learn to impose a grid on a line to quantify the steepness of a line. They learn that slope is the ratio of vertical change divided by the horizontal change. They also learn that lines can have slope that are positive, zero,...

Students learn that the slope is ratio of change in y to the change in x. They find the slope of a line using the slope formula, and examine the characteristics of lines with positive, zero, negative, or non-defined slope.

Students will graph the equations and determine if the viewing window is appropriate for the graphs.
