The cost function y = 90 + 8X:
A)has a slope coefficient of -8
B)will intersect the y-axis at 8
C)has a slope coefficient of 8
D)is a curved line

Question

Quizplus · Accepted Answer

The slope coefficient of the cost function y = 90 + 8X is 8. This means that for every unit increase in X, the cost increases by 8 units. The y-intercept of the function is 90, which means that the cost starts at 90 when X is 0. The function is a straight line because it has a constant slope coefficient and does not involve any exponents or other non-linear functions. Therefore, option C is the correct choice.

The Cost Function Y = 90 + 8X
