Answer
(a) $(-8,0)$
(b) $ (8,0)$
(c) $ (8,0)$
Work Step by Step
(a) A point symmetric with respect to the x-axis means $(x,y)\to (x,-y)$, thus $(-8,0)\to (-8,0)$
(b) A point symmetric with respect to the y-axis means $(x,y)\to (-x,y)$, thus $(-8,0)\to (8,0)$
(c) A point symmetric with respect to the origin means $(x,y)\to (-x,-y)$, thus $(-8,0)\to (8,0)$
