The last two answers are correct. You have to simplify the equation, firstly by distributing -3: y+5 = -3(x-1) y+5 = -3x+3 If you don't understand why that is done, Google PEMDAS or the order of operations. The rest of the simplification would look like: y=-3x-2 because you subtract 5 from both sides to isolate the Y.
