When using the visual-fit method to estimate a cost function, we can estimate the fixed cost by ________.

1) the point where the sketched line (through all or most of the data points) intersects the y-axis

2) calculating the variable cost per unit of the cost driver

3) the point where the sketched line (through all or most of the data points) intersects the x-axis

4) subtracting the variable cost at any cost driver level from the total cost
