Is it a Linear Function?

Front

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 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 value of y when x is 0; it is the point where the line crosses the y-axis.
