An equation of a line for all costs is
A) y = vx - f.
B) y = fx + v.
C) y = f.
D) y = vx + f

Question

Quizplus · Accepted Answer

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In the context of cost, the slope represents the rate of change of the cost per unit, and the y-intercept represents the fixed costs. Thus, the equation of a line for all costs is y = vx + f, where v is the cost per unit and f is the fixed cost. Choice D matches this form.
