1.
a set of two or more equations that share the same variables, and you solve them by finding values that satisfy every equation at once
2.
Two or more inequalities containing common variable(s)
3.
Any and all value(s) of the variable(s) that satisfies an equation, inequality, system of equations, or system of inequalities
4.
a method for solving a system of equations by isolating one variable in one equation and then replacing that expression into the other equation
5.
a technique for solving a system of linear equations by adding or subtracting the equations to cancel out one variable, leaving a single equation in one unknown that you can solve directly
6.
the line that separates a coordinate plane into two halves (called half-planes) when graphing a linear inequality.
7.
an ordered pair (x, y) chosen from a coordinate plane to determine which region of a graph satisfies a linear inequality
8.
The number multiplied times a product of variables or powers of variables in a term
9.
one of the four sections created when the x-axis and y-axis divide the coordinate plane
10.
y = mx + b, where m is the slope and b is the y-intercept
11.
