## Components of y = mx + b

In the equation y = mx + b, y represents the dependent variable, x illustrates the independent variable, m represents the slope, and b represents the y-intercept. These components are important in understanding the equation and its uses to real-life problems.

The dependent variable y depicts the output of the function, whereas the independent variable x represents 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 while x is equal 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 means that as x increases, y increases, whereas a negative slope means that as x increases, y decreases. A slope of zero means that there is no modification

alter in y as x increases.

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

## Examples of y = mx + b

The equation y = mx + b is utilized to depict a linear relationship within two variables, and it has many uses in various fields, including engineering, science, and finance.
