Final answer:
The new location after reflection across the y-axis in Quadrant III will have a negative x-coordinate and a positive y-coordinate.
Step-by-step explanation:
The new location after reflection across the y-axis in Quadrant III will have a negative x-coordinate and a positive y-coordinate. This is because reflecting a point across the y-axis changes the sign of the x-coordinate while keeping the sign of the y-coordinate the same. Since the original point is in Quadrant III, which has negative x and y values, the reflected point will have a negative x-coordinate and a positive y-coordinate. Therefore, the correct options are:
- The new location has a negative x-coordinate and a positive y-coordinate.
- The new location has negative x- and y-coordinates.
