ax + by = c dx + ey = f Using statement A, we can modify the equation ax + by + c to k(dx+ey=f) => We cannot find the point (x,y). Using statement B, we can change the equations to x + y = c and 2x + 2y = f (f not equal to 2c) As the slopes are equal and the intercepts are not equal, we can say that the equations do not have a solution. Hence, we can answer the question using statement B but not A.
