see explanation.
Explanation:
x+y=0 is the equation y=−x in disguise
this tells us that every y-coordinate is the negative of the
corresponding x-coordinate
⇒x=2→y=−2⇒(2,−2)
⇒x=1→y=−1⇒(1,−1)
⇒x=0→y=0⇒(0,0)
⇒x=−1→y=1⇒(−1,1)
plot these points and draw a straight line through them
graph{-x [-10, 10, -5, 5]}
