First, find the gradient of line A. We know that the line passes through the points (1, 3) and (4, 9). To calculate the gradient, find the difference in the y coordinates and the difference in the x coordinates, and then divide the y value by the x value. 9 - 3/4 - 1 = 6/3 = 2. The gradient of line A is 2.
One government expert calculated that a construction worker earning $31,200 a year before taxes would be left with an annual net compensation of $10,660.80 if paid as an independent contractor, compared to $21,885.20 if paid properly as an employee.
The distinction between employees and independent contractors is important, because an employer must withhold federal and state income taxes from employees, but not from independent contractors. Employers also must withhold Social Security/Medicare taxes from employees and must pay an equivalent amount to the Social Security Administration.
