Solutions to a System of Equations | A point on a graph (x,y) is a __________ if it makes all equations true |
Graphs of Equations | The set of all points (x.y) that make the equation true . The equation is true if a point (x,y) lies on a graph of the equation. |
Solving a System of Equations Graphically | When ________________, you find the intersections of two graphed lines |
Solving a System of Equations by Using Substitution | Substituting one equation into the other equation in a system of equations. Once the value for either x or y is found, find the other value by substituting your first answer into any original equation. |
Solving a System of Equations by Using Elimination | Eliminating either x or y by subtracting or adding all values together so x or y is equal to zero. To find the other value, substitute your original answer into any of the equations. |
Solutions to a System Remains a Solution if ___________________... | (1) Properties of equality are used to rewrite either of the equations, and (2.) the equations are added or subtracted or any rewrite is added or subtracted. |
System of Inequalities | Two or more inequalities |
