-x-y>-4
multiply two sides with -1 and change the sides when you multiply with negative numbers
4>x+y
draw the equation 4=x+y

now we will all domain and ranges will be found in one side of this equation (but do not include the line to then terriority)

the easiest way to find out which is to take origin (0,0) as an example.

4>0+0
4>0

yes it does fit so the left side of the equation is the correct side to choose and all you have to do is painting or filling the left side of the line (dont include the line by showing it in dot form (like this .........))
