Picture the solution. The Mathispower4u Algebra I video uses three examples of finding the solution of a system of linear equations given as a graph. Pupils use their knowledge of linear graphs to also identify the equations for the...

You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line...

You've got a linear system of inequalities? You need to solve it by graphing? No sweat. Make sure that each equation is in slope-intercept form and then graph each equation. Is it a solid line or a dashed line? Which side of the line...

Show your class how to check their answers for a system of linear equations. This video clarifies how to plug in answers and solve each equation. This is a straightforward video that could be useful to learners as the work on their...

Two equations. What's the solution to this system? How can you solve it? Can you write the two equations in slope-intercept form? Yes, you can. Now graph each equation. Look, the lines intersect. What does that mean? That means that...

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

In this set of activities, matrices and equations are explored. They work with matrices using pen and paper as well as graphing calculator. Additionally real-world problems are explored. 

Now that learners figured out how to solve for one variable, why not add another? The instructional activity demonstrates, through examples, how to solve a linear system using graphing, substitution, and elimination.

Solving systems by substitution can be a challenging topic in algebra I. Here is a lesson that builds on students' understanding of intercepts to begin the process of substitution, and all work is reinforced graphically to build...

Why do I have to learn two different ways to solve linear-quadratic systems? Isn't one way enough? Learners first investigate the three possible situations for linear-quadratic systems (two, one, or zero solutions), then solve such...

Students solve systems of equations with radical expressions. After reading real life situation, they translate the problem into algebraic expressions. As a class, students solve quadratic equations and inequalities by graphing and...

In this linear systems learning exercise, learners solve systems of equations using three different methods: substitution, adding and subtracting, and graphing. This two-page learning exercise contains three multi-step problems.

Young scholars read real world problems, determine the variables, and set up the function using algebraic statements. After entering data into the graphing calculator, they display information in the form of graphs and scatter plots. ...

Learners engage in a lesson plan that is about relational functions with the application of methods to real life problem situations. They use the examples found in the lesson plan for the purpose of practice during guided instruction....

High schoolers investigate the concept of using quadratic data to plot coordinates on a plane. They also apply the quadratic formula for a variety of problems with the help of a graphing calculator to draw the parabola for given...

Students create graphic, algebraic and verbal ideas of functions. In this algebra lesson plan, students graph functions and identify the zeros of the functions. They find the domain and range and classify functions as relation or not.

In this Algebra II activity, 11th graders use the quadratic formula to solve quadratic equations and examine the discriminate to determine the number and type of roots a quadratic equation will have.  The two page activity contains...

Students investigate the concept of functions and how they are used with polynomials. They practice finding the zeros of functions and graph polynomial functions for the help of giving solutions. Students interpret the curve of a line...

Students investigate the concept of exponential functions and how they increase in size over time. They simplify the functions in order to find the solutions that are possible and perform analysis of the curved line that is produced when...
