math

A function is a relation in which each input value (x) corresponds to exactly one output value (y).

The range is the set of all possible output values (y-coordinates) of a function.

In a linear function, the dependent variable is y.

A relation is a set of ordered pairs, where each pair consists of an input value and its corresponding output value.

The domain is the set of all possible input values (x-coordinates) for a function.

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise over run).
