    It's infinite because You can take the first equation x = -4y + 4, multiply the whole thing by two to get: 2y = -8y + 8 Then add 8y to both sides to get: 2y + 8y = 8 Hey, what do you know? It becomes the same as the second equation. Two equations that are the same have the same solutions, therefore the solution is infinite.
