Check the graph below, please
1) The first thing to do in this question is to find the lines, to do that we need to rewrite them as equations just to know where the lines are in the graph
2) So, let's set two t-tables for x+y=1 and 2y=x-4. Then we'll insert random values for x, and then we plug these values into the function to get the y-values
So we get the points (-2,3), (-1,2), (0,1), (1,0), (2,-1)
And now the second t-table, note that we need to rewrite it into the Slope form for convenience:
So the points (-2,-3), (-1,-2.5), (0,-2), (1,-1.5), (2,-1)
Note that these inequalities are greater than and lesser than, so we'll trace dashed lines
The darkest region represents the area where the possible solutions are.
