The equation y = Mx + b represents the slope-intercept form of a straight line.
To explain this
Each term in the equation has the following meanings:
y: This stands for the dependent variable, whose value is determined by the value of x. Typically, we associate it with a point's y-coordinate on a line.
M: This stands for the line's slope. It indicates the amount that y varies for each unit change in x. A positive M indicates a rightward movement, a negative M denotes a downward movement, and a zero M indicates a horizontal movement.
x: This stands for the independent variable, whose value is selectable. Typically, we associate it with a point's x-coordinate on a line.
b: This denotes the line's y-intercept, or the point at which it crosses the y-axis. The value of y is only b when x is zero, which indicates that you are looking at the place where the line meets the y-axis.
The fact that b cannot be utilized for y should be noted. They stand for various ideas. Y is the general value of y for any given value of x, whereas b is the value of y for a particular point (the y-intercept).
