Answer
(a) $ (5,3)$
(b) $ (-5,-3)$
(c) $(-5,3)$
Work Step by Step
(a) A point symmetric with respect to the x-axis means $(x,y)\to (x,-y)$, thus $(5,-3)\to (5,3)$
(b) A point symmetric with respect to the y-axis means $(x,y)\to (-x,y)$, thus $(5,-3)\to (-5,-3)$
(c) A point symmetric with respect to the origin means $(x,y)\to (-x,-y)$, thus $(5,-3)\to (-5,3)$
