Which quantity is best modeled by a linear function

See the explanationExplanation:Since you haven't provided any options I'll face this problem in a general way. Linear functions are given of the form:[tex]y=mx+b[/tex]This is called the slope-intercept form of the equation of a line. When modeling a linear function we need to take into account that we will have a constant rate of change and that when plotting our model this will follow a line. In order to model a problem as a linear function we need to follow some tips:Identify the changing quantities in order to define the variables that stands for them.Draw a diagram or a coordinate system. It is usual to use the Cartesian coordinate system.Read the problem in detail.Set a mathematical model writing the equation that stands for the problem.Set values into the variables in order to check your model.Check your results.Learn more:Linear function:
