## Elements of y = mx + b

In the equation y = mx + b, y illustrates the dependent variable, x depicts the independent variable, m portrays the slope, and b represents the y-intercept. These elements are essential in getting a grasp the equation and its uses to real-world problems.

The dependent variable y illustrates the output of the function, while the independent variable x illustrates the input. The slope m represents the change in y over the change in x, and the y-intercept b illustrates the value of y while x is equivalent to zero.

The slope (m) can be positive, negative, or zero, and it figures out the course and steepness of the line. A positive slope implies that as x increases, y increases, whereas a negative slope states that as x increases, y decreases. A slope of zero states that there is no change in y as x increases.

The y-intercept (b) is the point where the line bisects the y-axis. It implies the value of y while x is equal to zero.

## Examples of y = mx + b
