Elements of y = mx + b
In the equation y = mx + b, y depicts the dependent variable, x represents the independent variable, m represents the slope, and b depicts the y-intercept. These elements are important in getting a grasp the equation and its utilizations to real-life challenges.
The dependent variable y depicts the output of the function, whereas 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 depicts the value of y while x is equal to zero.
The slope (m) can be positive, negative, or zero, and it determines the direction and steepness of the line. A positive slope states that as x increases, y increases, whereas a negative slope states that as x increases, y decreases. A slope of zero means 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 represents the value of y when x is equal to zero.
Examples of y = mx + b
