Is there another way to solve this proportion problem
y – 1 = -3
x + 3 4
4(y - 1) = -3(x+3) The result of cross multiplying.
4y – 4 = -3x - 9 Distribute 4 on the left and -3 on the right.
4y – 4 + 4 = -3x – 9 +4 add 4 from both sides
4y =-3x- 5 Divide both sides by 4
4 4
y= -3x - 5 or y =-3x-5
4 4

I don't think I see "this proportion problem"

phi · Answer

it looks ok, until the last line
$$ y= - \frac{3}{4}x- \frac{5}{4} $$
that is ok.  but that is as far as you can go.  You can not drop the divide by 4's
