Hi

i) abs(x) + abs(y) = 1

ii) abs(x+y) = 1

iii) abs(x) - abs(y) = 1

iv) abs(x-y) = 1

v) 2*abs(x) + abs(y) = 1

Could someone please show me how to sketch these absolute value graphs? I've found examples on the easier versions in textbooks but they don't cover these types of graphs. (I'm just trying to learn next year's stuff so I don't fall behind.)

Thanx very much
