They are the same line
Step-by-step explanation:
When you have equations of line and want to compare them, make sure the y is isolated (by itself)
the second equation -2y = 4x-8 is not isolated
To isolate, divide both sides by -2
[tex]\frac{-2y}{-2} =y[/tex]
[tex]\frac{4x-8}{-2} = -2x+4[/tex]
Now you have y=-2x+4, which is the same equation as the first!
(remember that if you divide a negative number by a negative number, you will get a positive one)
