Answer
$(3., -5)$
Work Step by Step
RECALL:
In the point $(a, b)$, $a$ is the directed distance of the point from the $y$-axis (positive when to the right of the $y$-axis) and $b$ is the directed distance from the $x$-axis (positive when above the $x$-axis).
The point is:
$3$ units to the right of the $y$-axis means $x=3$
$5$ units below the $x$-axis means $y=-5$.
Thus, the coordinates of the point are $(3, -5)$.
