Linear Functions Teacher Resources

Learn how to write equations for linear functions in all three forms: point-slope, slope-intercept, and general. Also look at equations for parallel and perpendicular. The page gives an explanation of how to obtain the point slope form...

This website introduces the concept of linear functions in slope intercept form.

[Free Registration/Login may be required to access all resource tools.] Here you'll learn how to convert an equation to function notation and how to input a value into a function in order to get an output value.

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]

This video tutorial demonstrates how to graph linear equations on the coordinate plane using only the x- and y-intercepts. Students can check their understanding with an assessment.

In this activity, students take distance readings as they walk in front of a CBR. They apply the properties of a linear function to develop a model for the motion and interpret the values used in the model. Students learn to graph...

In this activity, students write rules for real world functions. They make a table to compare function values and graph linear functions on the coordinate plane.

Analyze the numerical and graphical representations of functions. This interactive exercise focuses comparing linear, quadratic, and exponential functions and their graphical representations after completing a table to calculate ordered...

Students can use their knowledge of linear functions to match real world linear situations. Students will be asked to match equations to linear pictures that are imposed in a coordinate plane.

[Free Registration/Login may be required to access all resource tools.] In this tutorial, students learn to write and evaluate functions and determine if a graph represents a function. They examine guided notes, review guided practice,...

This video explains how to compare the slopes and intercepts of two linear functions that are represented in different forms. [5:06]

In this activity, students create a situation that produces linear behavior by stepping heel to toe and taking distance readings as each step is taken. Students then apply the properties of a linear function to develop a model for motion.

In this task involving temperature conversions, students construct a linear function given two input-output pairs, investigate the inverse of a linear function, and reason about quantities and/or solving a linear equation. Aligns with...

Graph the line 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.

In this lesson concept we use the Activity Center to build some basics in students understanding of linear functions. The linear relationship is clearly one of the big ideas of the algebra curriculum, and it paves the way for a deeper...

Explore the relationship between slope and the constant rate of change for linear functions. Assess learning with a quiz. [3:42]

For this task, students are asked to find a linear function which models the number of households in the U.S. as a function of the year. They are also to construct and use an inverse function to model the context, and interpret their...

In this activity, students collect information about the stops made, time taken, and distance covered by a train on one of Amtrak's routes. They find a mathematical model that can best track the train. Students understand concepts...

Students learn how to create a table of values for a simple linear function and use the table to create a graph on squared paper. They use the graphing calculator to display the ordered pairs and find values of corresponding to values of...

For this task, learners investigate the changes that take place in the values of a function to determine that linear functions grow by equal differences over equal intervals. Aligns with F-LE.A.1.a.

In this activity, students use linear functions to model and solve problems in situations with slope and a constant rate of change. They learn to represent situations with variables in expressions, equations, and inequalities and use...

This StudyCard stack teaches that, when linear functions are added, the slope of the sum is equal to the sum of the slopes, likewise for y-intercepts. Includes quadratic and up polynomials.

Students learn to use measurements on a real model to develop the concept of slope and linear functions. They use a calculator to explore changing the slopes and Y- intercepts in the slope intercept form Y = MX + B.

Here is a site that clearly and thoroughly explains linear functions and the equation of a straight line. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to...
