Answer
$-2$; $4$
Work Step by Step
RECALL:
The point $(x, y)$ has:
$x$ = directed distance of the point from the y-axis (negative when to the left of the y-axis, positive when to the right)
$y$ = distance of of the point from the x-axis (negative when below the x-axis, positive when above)
Thus,
2 units to the left of y-axis means $x=-2$
4 units above the x-axis means $y-4$
The point is $(-2, 4)$.
