Hello there!

To find this, we must simplify this equation.

first, let's simplify the right side

-1 * x = -x

-1 * 5 = -5

Now, we have: y -3 = -x -5

Now we must add + 3 to each side to get rif of the negative three

now we have y = -x - 2

So, your answer is B.) y= -1x - 2

I hope my answer was of assistance!
