## Elements of y = mx + b

In the equation y = mx + b, y represents the dependent variable, x illustrates the independent variable, m portrays the slope, and b depicts the y-intercept. These components are crucial in understanding the equation and its application to real-life challenges.

The dependent variable y represents the output of the function, while the independent variable x represents the input. The slope m depicts the change in y over the change in x, and the y-intercept b illustrates the value of y when x is equivalent 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, while a negative slope implies 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 crosses the y-axis. It implies the value of y when x is equal to zero.

## Examples of y = mx + b
