1-2 Solving Linear Systems Goal: To be able to solve linear systems by graphing, substituting, and elimination
What is a linear system? Solving by graphing Solving by substitution Solving by elimination Graph the two equations on the same coordinate plane. Isolate a variable in one equation Use the appropriate operation to get rid of one variable The point of intersection is the solution. Ex. (1,2) Substitute the resulting expression in the other equation. Then solve the remaining equation
Don’t Forget!!!! To write final answers in (X, Y) form. Ex. (1, 2) Follow instructions on how to solve linear systems! You can always check your work with any method! Dance while you are graphing!
