Systems of Equations and Inequalities
Algebra II Terms
Get down with the lingo
Coordinate SystemA diagram for visually graphing equations using x-, y-, and z-axes. Stare at it long enough and you'll find the hidden 3D image.
Elimination MethodA method of solving a system of linear equations where the two equations (or multiples of the equations) are added or subtracted to eliminate one of the variables. It's the recipient of the Shmoop Personal Favorite Method For Solving Linear Equations Award.
Ordered TripletA set of three elements written as (x, y, z). Please don't call them Fred, George and Shirley. That's confusing.
SolutionThe points that satisfy all equations in a system. Not just one out of two, two out of three, or 137 out of 138.
Substitution MethodA method of solving a system of linear equations where one equation is solved for one of the variables and then that equation is substituted in for the variable in the other equation. It's the runner-up for the Shmoop Personal Favorite Method For Solving Linear Equations Award.
System Of Linear EquationsTwo or more linear equations with variables x and y, and maybe others. Usually they will be unknown values. If you know what they are, it really takes the sport out of solving linear equations.
