How would I turn the point-slope form linear equation into standard form? Y - 3 = 3 (x + 1)

How would I turn the equation Y = 3x + -3 into standard form?

I had to turn the equation, y - 3 = 3 (x + 1), into a perpendicular line that passes through (5,-1) and I got y = -1/3x + 2/3. Would the standard form of this be 1x + 3y = 2? I then have...
