3-1 Learning Targets

I understand the solution to a system of equations is an ordered pair point that satisfies both equations. Geometrically, this is the point where the graphs intersect.

I can solve a system of equations by graphing (by hand or using technology)

I can solve a system of equations by using the substitution method.

I can solve a system of equations by using the elimination method.
