Systems of Equations

Match the following:

• any ordered pair that makes all equations in the system true

• Substitution

• Finding the solution of a system by where they intersect on a graph

• Graphing

• Finding the solution of by replacing a variable in one equation for what the variable equals

• Inspection

• Finding how many solutions there are just by looking at the equations in y=mx+b

• System of linear equations

• two or more linear equations that use the same variables

• Solution of a system of linear equations
