## Components of y = mx + b

In the equation y = mx + b, y illustrates the dependent variable, x illustrates the independent variable, m portrays the slope, and b illustrates the y-intercept. These components are essential in understanding the equation and its uses to real-world challenges.

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

The slope (m) could be positive, negative, or zero, and it figures out the course and angle of the line. A positive slope means that as x increases, y increases, whereas a negative slope means 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 states the value of y when x is equivalent to zero.

## Examples of y = mx + b

The equation y = mx + b is utilized to depict a linear relationship between two variables, and it has many applications in various domains, consisting of science, engineering, and finance.
