{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable  y Â
Â
 7y = 7x + 28
 y = x + 4
Plug this in for variable  y  in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable  x Â
4x = - 8 Â
x = - 2
By now we know this much :
  x = -2
  y = x+4
Use the  x  value to solve for  y Â
  y = (-2)+4 = 2
Solution :
and this intersects at only one point so your answer is A
