Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

What is a y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if a line has a positive slope?

Back

It means that as x increases, y also increases.

Front

What does it mean if a line has a negative slope?

Back

It means that as x increases, y decreases.

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What is the difference between a function and a relation?

Back

A function assigns exactly one output for each input, while a relation can have multiple outputs for a single input.

Front

What is a linear function?

Back

A function that graphs to a straight line.

Front

What is the domain of a function?

Back

The set of all possible input values (x-values) for the function.
