which of the following statements related to CVP chart is not true?

a. the high-low method is a way to estimate the cost behaviour by graphically connecting the two cost amounts identified with highest and lowest volume levels

b. to determine the variable cost per unit from a graph, the change in cost is divided by change in units

c. the slope of the total cost line determines the variable cost per unit

d. to calculate the total fixed cost from a graph is by multiplying a level of volume by the variable cost per unit found out earlier and subtracting that from total cost for that level of volume

e. none of the given answers

f. the intercept between the total cost line on graph and the y-axis determines variable cost
