What is a linear function?

Back

A linear function is a function that can be graphically represented as a straight line. It has the form y = mx + b, where m is the slope and b is the y-intercept.

What is a nonlinear function?

Back

A nonlinear function is a function that does not form a straight line when graphed. It may include curves, bends, or other shapes.

How can you identify a linear function from its equation?

Back

A linear function will have no exponents greater than 1, no products of variables, and no variables in the denominator.

What does the slope (m) represent in a linear function?

Back

The slope (m) represents the rate of change of the function; it indicates how much y changes for a unit change in x.

What does the y-intercept (b) represent in a linear function?

Back

The y-intercept (b) is the point where the line crosses the y-axis, indicating the value of y when x is 0.

What is the general form of a linear equation?

Back

The general form of a linear equation is Ax + By = C, where A, B, and C are constants.

Front

What is the significance of the graph of a linear function?

Back

The graph of a linear function shows the relationship between the independent variable (x) and the dependent variable (y) in a visual format.

What are the characteristics of the graph of a linear function?

Back

The graph of a linear function is a straight line, has a constant slope, and can extend infinitely in both directions.
