Graphic lesions to solve the system y equals 1/3 x +6 and why equals 1/3 x +4

For this case we have the following functions:
 y = (1/3) x + 6
 y = (1/3) x + 4
 We note that both lines have the same slope in this case given by:
 m = 1/3
 Therefore, the lines are parallel.
 As they are parallel, they are not cut at any point.
 Thus, the system of equations has no solution.
 
 The system has no solution (parallel lines)
