I'm am trying to solve -4x +4y > 8 I understand to add 4x to both sides which would bring it to 4y >8+ 4x now do I subtract 8 on both sides or -4y. I am trying to find the x, y points to graph

Your inequality reduces to:
y > x + 2
Can you plot
y = x + 2

[I] am trying to solve -4x +4y > 8 [for y]
I understand to add 4x to both sides which would bring it to 4y >8+ 4x Correct!
now do I subtract 8 on both sides or -4y.
Neither. To solve for y, you divide both sides by 4
