Rather than giving a website, let's try to work it out together. First we need to figure out the slope of our line, and since we have a different line it's parallel to, we can use that to figure out our slope. x+y=3 in point-slope form is y=-x+3, so our slope is -1. Now to figure out our y-intercept, we plug in the point given into the point-slope equation and we gave -1=-1(-1)+b, which gives us b=-2. So the equation is y=-x-2. Makes sense?
