Solutions to Systems of Linear Equations

Type: Learning Activity


Students will use a Desmos activity to find solutions to systems of linear equations. This activity will help students understand what it means for a point to be a solution to a system of equations–both graphically and algebraically. This Desmo activity offers sample student responses and a teacher guide.

Content Standard(s):
MA2015 (2016)
Grade: 9-12
Algebra I
20 ) Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables. [A-REI6]

Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.A.HS.20- Name the coordinate pair of the intersection of two lines in a coordinate plane.

Desmos's mission is to help every student learn math and love learning math. Teachers can explore and enjoy Desmos collections of free digital math activities that include:

  • Meaningful feedback by showing students what their answers mean, then give them the opportunity to improve their thinking and revise their work.
  • Collaboration by using devices to connect students, not to isolate them. Students see their classmates' thinking. They ask each other questions and create challenges for each other.
  • Invites students to solve challenging problems using the tools they already have.

If the teacher does not have an account, he/she will need to create a FREE account. (More information on how Desmos works can be found at Getting Started.)


Once the teacher has selected an activity to run, he/she will need to click on the "Create Class Code" button. This will generate a unique class code and a link to view the dashboard. (More information can be found at Creating a Class Code.) Every new activity will need a new class code in order to start a session. Students cannot start the activity until they have the class code so sessions can be started days, hours, or mere minutes before the teacher plans to run the activity. When the teacher is ready to have students start, have the students go to and enter the class code. Although it is not required, Desmos strongly encourages students to sign in with their Desmos Student Account. Signing in allows students to resume and view their past activity work.
