What is the definition of a linear function?

Back

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

What is the absolute value function?

Back

The absolute value function, denoted as |x|, returns the non-negative value of x. For example, |3| = 3 and |-3| = 3.

How do you determine if a function is linear from its equation?

Back

If the equation can be written in the form y = mx + b, it is linear. If it includes variables multiplied together or raised to a power, it is nonlinear.

What is the meaning of the term 'slope' 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.
