Tell whether the system below has 1 solution, no solution, or infinitely many solutions. If the system has a solution, find it.

1.
y = 6x + 1

y = 6x - 1

________________ 		2.
y = 3x + 1

y = 2x - 1

________________
3.
y = -5x + 1

y = -5x + 1

________________ 		4.
y = 8x - 5

y = -8x - 5

________________
5.
2y - 6x = 10

2y + 6x = -10

________________ 		6.
10y = 20x + 40

10y = 20x + 10

________________
7.
y = (1/5)x - 2

5y + 10 = x

________________ 		8.
y = (1/4)x + 6

4y - 24 = -x
