## Elements of y = mx + b

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

The dependent variable y illustrates the output of the function, whereas the independent variable x depicts the input. The slope m illustrates the modification 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 determines the course and steepness of the line. A positive slope states 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 bisects the y-axis. It represents the value of y while x is equivalent to zero.
