Systems of Linear Equations
A System of Linear Equations: a set of two or
more linear equations that are to be solved at the same time.
A Solution to a System: an order pair that is
a solution to every equation in the system.
Solving a Linear System Graphically: graph
the equations on the same coordinate plane. The coordinates of
the point of intersection are the ordered pair solution.
Consistent System: a system with at least one
Inconsistent System: a system with no
solutions (the lines are parallel).
Dependent Equations: equations whose graphs
Independent Equations: equations whose graphs
do not coincide.
