Domain

The ______________________ is all the possible INPUT, X, values.

function

If you repeat an INPUT, and you always get the same OUTPUT, your data is a ______________________ .

function rule

An equation that describes a function.

Linear Equation

A polynomial equation of the first degree whose graph is a line.

linear inequality

contains a single variable on either side of the inequality symbol.

negative correlation

y tends to decrease, as x increases

no correlation

The values show no relationship.

positive correlation

y tends to increase, as x increases

Range

The difference between the greatest number and the least number in a set of data.

Relation

A Smart Art graphic type that compares connections between concepts.

Scatter plot

is a graph used to determine whether there is a relationship between paired data. Scatter plots can show trends in data.

slope

(y₂-y₁)/(x₂-x₁)

Slope-Intercept Form

a linear equation written in the form y = mx + b, where m represents slope and b represents the y-intercept

Solution

The value or values that make an equation or inequality true.

line of best fit

The line that most closely follows a trend in data is called the best-fitting line.

vertical-line test

The test that visually determines whether or not a relation is a function or not.

y-intercept

the point where the line crosses the y-axis

point-slope form

Given a point (x₁, y₁) and slope m

standard form of a linear equation

Ax + By = C, where A,B, and C are real numbers, and A and B are not both zero.

x-intercept

the point where the line crosses the x-axis
