(d) Sketch the graph of all points (x,y) which satisfy {x} + {y} = 1
(e) Sketch the graph of all points (x,y) which satisfy |x| + |y| = 1
For (a), does the graph look like a series of repeated triangles on the x-axis? (b) and (c) are similar to (a).
And I can't figure out (d) and (e)... hints/insights would be great. Thanks in advance!
