Failure is NOT an option!

Scale #1 – Solving a System of Equations Graphically

Level 3:

Level 2:

Scale #1 – Solving a System of Equations Graphically

Level 3: Solve real world and mathematical problems leading to two linear equations in two variables graphically

A system of equations is a set of two or more equations that contain two or more variables.

Scale #1 – Solving a System of Equations Graphically

Level 2: Graph two linear equations on one coordinate plane

Level 2: Write an equation in slope intercept form

Level 2: Understand that the solution to a system of two linear equations in two variables corresponds to the points of intersection of their graphs

Level 3: Solve real world and mathematical problems leading to two linear equations in two variables algebraically

Scale #2 – Solving a System of Equations Algebraically

Level 2: Solve linear equations algebraically

y = x + 3

A solution of a system of equations is a set of values that are solutions of all of the equations. If the system has two variables, the solutions can be written as ordered pairs.

Wrap UpToday we introduced unit 5 and identified solutions to system of equations. We also worked on a level 2 skill for solving a system of equations by graphing. You need to be able to graph a couple of lines on the same graph to find a solution to a system of equations graphically.
