The correct representation of the graph of any nonvertical line is given by:
B y = mx + b
In this equation, \(y\) represents the output (dependent variable), \(x\) represents the input (independent variable), \(m\) is the slope of the line, and \(b\) is the y-intercept (the point where the line crosses the y-axis).
Options A, C, and D do not represent the standard form of a linear equation.
