One even answering one me a lot : ) : ) : )

1)
2y = -x + 6
x + 2y = 6 ...this is standard form

2)
9x + 2y = 6
2y = -9x + 6
  y = -4.5x + 3 this is slope intercept form

3)
y - 3 = 4(x + 1)
y - 3 = 4x + 4
4x - y = -7  this is standard form

4)

y + 7 = -2(x - 3)
y + 7 = -2x + 6
y = -2x - 1 this is slope intercept form

hope it helps
