Linear functions are the functions whose graph is a straight line.
The information is incomplete. Therefore, an overview will be given. A linear function has the following form. y = f(x) = a + bx. It has one independent variable and a dependent variable.
A linear function is represented by the equation y = mx + b where:
y: the y-coordinate.
m: the slope of the line.
x: the x-coordinate.
b: the y-intercept
I calculus and related areas, the linear function is a function where the graph is a straight line, which is, a polynomial function of degree zero or one.
