Best-fit Line

A precise line of fit

Bivariate Data

data with two variables

Constant Function

a graph of y=0, or a horizontal line with a slope of zero.

Constraint

Correlation Coefficient

A number that a calculator may compute that tells you if your correlation is positive or negative, and tells you how closely the equation is modeling the data.

Identity Function

A parent function

Inverse Function

a function that can generate ordered pairs of the inverse relation

Inverse Relation
