c
because you want to get everything but y to one side. So, subtract x from each side
-y = 4 - x
and divide each side by -1
y=-4 + x which is the same as y=x-4

well it aint gonna work because I think you mean y= mx + b
given you understand the problem, then:
x-y = 4 is changed to
-y= 4 -x
which cleans up to
y = -4 + x
which becomes
y= x-4 (c)

y = mx + b
for x - y =4, add y to each side and add -4 to each side
y=x-4, in this case m=1 and b=4

How about y=mx+b:
Both a and c are correct

the answer is d.y=x+4.y first,x and m=slope and 4 at the end for b.

y = mx + b
x - y = 4
move y to other side
x - 4 = y, so its c
