For this task, students are shown the graphs of two equations, with areas bounded by their lines and intersections shaded in different colors. They are asked to write a system of equations or inequalities for each shaded area and explain...

Students are required to solve a system of equations in this task which will demonstrate their understanding of the correspondence between intersection points of the two graphs and solutions of the system. Aligns with A-REI.C.7.

For this problem, students must determine how much quinoa and how much corn are in a type of pasta. They must study the ingredient list which shows the protein content of the pasta. They know that quinoa has more protein than corn and...

[Free Registration/Login may be required to access all resource tools.] Given a set of constraints, graph and solve linear problems.

This lesson presents how to use elementary row operations to solve for a system of linear equations.

This lesson is a review of problems with systems of inequalities. Many of the questions involve real world scenarios as word problems which the reader must decipher and resolve.

Practice the connection between the graphical representation of equations and their algebraic solutions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

[Free Registration/Login Required] This flipchart provides guided practice with word problems involving systems of equations and gives a brief review on solving systems of equations.

A brief overview of three methods used to graph lines is presented through examples. Slope-intercept, point-slope, and intercept form are demonstrated step-by-step along with a review of the formula for finding the slope of a line.

The purpose of this task is to give young scholars the opportunity to make connections between equations and the geometry of the graphs. Aligns with A-REI.C.7and A-REI.D.10.

This illustrated math instructional activity shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth...

The resource consists of comprehensive notes, videos, and worksheets through which students can review algebra concepts.

Based off of the hit television show NUMB3RS, this lesson shows students a real-world application to matrices and matrix operations. Framed in the context of a stolen painting which the thief may hide at different warehouses, students...

In this lesson, the Gaussian Elimination method is used to solve systems of linear equations. Provides several formulas and examples for understanding.

Cramer's Rule for solving a system of equations is presented here using an example of a system in three variables with three equations. The "everything," approach of solving for all three variables is shown as well as the "selective,"...

In Spanish. Learn the algebraic language to represent and solve systems of two linear equations with two unknowns.

For this problem, students must determine how much of a quinoa-based gluten-free pasta is actually quinoa. They must study the ingredient list and set up linear equations to solve the problem. Aligns with A-REI.C.6.

In this lesson, students make observations about the motion of a boat going up and down the river. They will solve the system of equations algebraically and graphically.

This task requires students to recognize the pairs of linear equations in two variables that would be used to solve a given system of equations. Aligns with A-CED.A.3.

Given the graph of a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or...

Given a two-variable linear inequality, check whether a given pair of values is a solution of the inequality. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

This lesson introduces students to Activity Center and is intended to help students develop the conceptual understanding of how to identify functions as linear or nonlinear and contrast their properties from tables, graphs, or equations.
