Back

radical

Front

another name for a square root

Back

system of linear equations

Front

Two or more linear equations to be solved at the same time (with the same variables)

Back

standard form

Front

when the terms of a polynomial expression or functions are arranged in 1) alphabetical order and 2) exponential order (from largest to smallest)

Back

parabola

Front

The graph of a quadratic function

Back

coordinate plane

Front

A coordinate system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.

Back

slope

Front

Rise over run; The steepness of a line on a graph; (y₂-y₁)/(x₂-x₁)

Back

GCF

Front

All of the input or x values in a function

Back

ordered pair

Front

A pair of numbers that can be used to locate a point on a coordinate plane, for example (3,2); also known as a coordinate or a point

Back

rational number

Front

Any number that can be written as a fraction; includes natural, whole, and integer numbers; includes decimals that end or repeat

Back
