Linear Equations (solve for y to put it into slope intercept form...y = mx+b). Are these 2 correct, please show me what I did wrong if not, thank you...

A) y-5 = -2(x-3)
y-5 = -2x+6 (add +5 to both sides)
y = -2x+11

B) if m = -2/1 = -2
y-0 = -2(x+4)
y = -2x-8

A is correct

B is correct if the line goes through (-4,0)
