slope intercept form

Front

A linear equation written in the form y=mx+b. The slope of the line is m. The y-intercept is b.

Back

reciprocal

Front

Two numbers are reciprocals if their product is 1. If a/b is a nonzero number, then its reciprocal is b/a

Back

distributive property

Front

you multiply a sum by multiplying each addend separately and then add the products.

Back

x-axis

Front

the horizontal axis in a coordinate plane

Back

coordinate plane

Front

The coordinate system formed by two real number lines that intersect at a right angle

Back

intercept

Front

The y or x-coordinate of a point where a graph crosses the y or x-axis.

Back

quadrant

Front

One of four regions into which the axes divide a coordinate plane

Back

variable

Front

a letter that replaces a number

Back

y-axis

Front

the vertical axis in a coordinate plane

Back

origin

Front

The point in a coordinate plane where the horizontal axis intersects the vertical axis. The point (0,0)

Back

solution of an equation

Front

A number that, when substituted for the variable in an equation or inequality, results in a true statement.

Back

scatterplot

Front

A coordinate graph containing points that represent a set of ordered points; used to analyze relationships between two real-life quantities.

Back

equation

Front

A statement formed by placing an equal sign between two expressions.

Back

slope

Front

The ratio of the vertical rise to the horizontal run between any two points on a line. rise over run

Back

inverse operations

Front

Two operations that undo each other, such as addition and subtraction.

Back

range

Front

The collection of all output values of a function

Back

ordered pair

Front

A pair of numbers used to identify a point in a coordinate plane. The first number is the x-coordinate and the second number is the y-coordinate (x, y)

Back

domain

Front

The collection of all input values of a function

Back

rate of change

Front

The quotient of two different quantities that are changing. In a linear model, the slope give the rate of change of one variable with respect to the other.

Back

order of operations

Front

The rules for evaluating an expression involving more than one operation.
