Answer:
(3, 4)
Step-by-step explanation:
When a point is reflected over both axes, its x-coordinate and y-coordinate are negated (change sign). The original point (-3, -4) reflected over the x-axis becomes (-3, 4), and then when this new point is reflected over the y-axis, the x-coordinate is negated again, resulting in (3, 4). Therefore, the coordinates of the new point after the double reflection are (3, 4).
