hi everyone, so i have a question, i was given this linear equation in the image uploaded. and the other image shows my working. now i know that the points cross at (1,1)
. that part that confuses me is that in the book it mentions that (-1,2) and (-2,1) belong to the shaded area. now i know that they obtained (-1,2) by this y= -x+2 = 1=-1+2
but can someone explain to me how they got the (-2,1) ? thanks
