Graphing Linear Equations Teacher Resources

Provide a continuous progression to linear and exponential functions. Pupils continue to work with the discrete functions known as sequences to the broader linear and exponential functions. The second unit in a series of nine provides...

The third example's the charm. Young mathematicians watch a helpful video that shows how to graph a linear equation in slope-intercept form on a coordinate plane. The narrator works through the example y = –2x + 5 by first plotting the...

Intersections become solutions. Scholars watch a video on using a graphing calculator to find the solution to an equation in one variable. While watching the presentation, pupils practice working some of the examples and compare their...

Class members must determine the best phone plan for customers. by assessing three different phone plans. Each plan price depends not only the number of minutes, but also the location of the calls — bringing in a third variable. Scholars...

Pupils explore the many representations of linear functions by completing a matching activity to connect the multiple representations of a function. They then reinforce the connection as individuals create the different representations...

Learners step up to the plate as they first complete an assessment task using linear equations to determine the best company from which to buy baseball jerseys. They then evaluate provided sample responses identifying strengths and...

Need lessons on writing and solving one- and two-step linear equations and inequalities, as well as systems of equations? This comprehensive 106-page module from the Georgia Department of Education contains many different lessons for a...

Future mathematicians use a given graph to answer a question about age differences in relationships. Along the way, they must find the equation and inequality of given graphs.

Y equals graphs are horizontal, but x equals graphs are vertical. Learners explore the connection between the graph and the equation of vertical lines while watching an instructional video. The presenter shows a set of ordered pairs...

Determining relationships is all part of algebra and functions. Your mathematicians will decide the type of relationship between airports and population and translate what the slope and y-intercept represent. The problem is multiple...

Graph the night away with all the different types of functions provided in the instructional activity. Linear, quadratic, and rational all ask for graphs, domain and range and other key factors about the functions.

Parallel parking might be difficult, but finding parallel lines is fairly simple. In this lesson, learners first complete an assessment task involving parallel and perpendicular lines in the coordinate plane. Individuals then take part...

What do the graph of a line and its equation have in common? This is the first question the video poses to scholars as they begin watching the lesson. The instructor then explains how to use the graph to write the linear equation.

What is my monthly payment? Scholars research to find the perfect car for them to buy. Using the cost of the car, they determine a down payment and the amount of monthly payments using a zero interest loan. Finally, they investigate what...

It makes sense that it's called the slope-intercept form. After reviewing how the slope and y-intercept affects the graph of a linear equation, individuals learn how to graph a linear equation given in slope-intercept form. They watch as...

The bounce of a golf ball changes the result in golf, mini golf—and a great math activity. Scholars graph the height of golf ball bounces before finding a line of best fit. They analyze their own data and the results of others to better...

Make sure pupils have the skills to move on to the second half of the module with a mid-module assessment task. The formative assessment instrument checks student learning before moving on to the rest of the lessons in the unit.

Build a strong understanding of graphing and writing equations of horizontal and vertical lines. Pupils watch as the lesson instructor explains how to graph horizontal and vertical lines from an equation. She then gives individuals an...

Graphs, functions, symbols, and more! Use these strategies to model everything from the flow of a river to the number of cars passing a toll booth. Presented differently but solved similarly, learners consider five different scenarios...

Water pressure decreases at a constant rate with a change in depth. A video lesson demonstrates how to use a linear equation to determine the depth when given a specific pressure. Learners must substitute for the dependent variable to...

Investigate the relationship between the gradient, or slope, of a line and its graph. Pupils learn to use a graph to calculate the slope of a line. The video lesson includes both positive and negative slopes and compares the steepness of...

Bypass the table and go straight to the graph. A short video shows one example of graphing a direct variation equation with a negative slope by using the same method as graphing an equation in slope-intercept form. Pupils see it's easy...

Pupils research the five most fuel efficient vehicles of the same type and come up with a way to display the mile per gallon for each vehicle. After choosing a vehicle, scholars create graphs to display miles traveled given the amount of...

Organize your learners with this well-laid-out note-taking printable. Note blanks are organized to allow for two strategies of graphing an equation given in standard form.
