which points are on the the graph equation -3x+6y+5=-7

Sagot :

-3x + 6y + 5 = -7
                -5    -5
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
               6y = -12 + 3x
                6           6
                 y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
       -3x - 12 + 3x = -12
         -3 + 3x - 12 = -12
                0x - 12 = -12
                     +12    +12
                       0x = 0
                        0     0
                         x = 0
           -3(0) + 6y = -12
                0 + 6y = -12
              +0             +0
                      6y = -12
                       6       6
                        y = -2
                  (x, y) = (0, -2)
