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 $(-2, 4)$.
