The equation below specifies a function with independent variable x. Determine whether the function is linear, constant, or neither. x = 3y +7 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The equation specifies a constant function, because it can be rewritten in the form y = b with b = (Simplify your answer.) O B. The equation specifies a linear function, because it can be rewritten in the form y = mx + b, where m #0, with m = and b= (Simplify your answers.) O C. The equation specifies neither a linear nor a constant function
