Answer 2

that might help

Answer 3

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?

Answer 4

x - y + 2 = 0
x + y + 2 = 0
x + y - 2 = 0

These are the options I have to choose from...

Answer 5

So it's x+y+2=0.

Oh ok thank you so much
