ok on this problem it says sketch the graph of the equation and label the coordinates of at least three solution points of y=2-x. I can find one point by substituting 0 in, but how do i find the second and third point.
this is how I found the first points
#1 ( 0,2 ) then for #2 #3 points i figured do the same for y, but the book has the second and third point as 1,1 and 3, -1. How did they get that?
