Rectangle RSTU is reflected around the x-axis and then around the y-axis to create rectangle R′S′T′U′. Which statement is true?(1 point)

If vertex R has negative x- and y-coordinates, vertex R′ will have a negative x-coordinate and a positive y-coordinate.
If vertex upper R has negative x - and y - coordinates, vertex upper R prime will have a negative x - coordinate and a positive y - coordinate.

If vertex R has negative x- and y-coordinates, vertex R′ will have positive x- and y-coordinates.
If vertex upper R has negative x - and y - coordinates, vertex upper R prime will have positive x - and y - coordinates.

If vertex R has negative x- and y-coordinates, vertex R′ will also have negative x- and y-coordinates.
If vertex upper R has negative x - and y - coordinates, vertex upper R prime will also have negative x - and y - coordinates.

If vertex R has negative x- and y-coordinates, vertex R′ will have a positive x-coordinate and a negative y-coordinate.
If vertex R has negative x- and y-coordinates, vertex R′ will have positive x- and y-coordinates.
Point K is on figure D has the coordinates (6,3). If it is reflected across the y-axis, what would the new coordinates be for the reflected point K?

(6,−3)
(3,6)

(−6,3)
(−3,6)
The reflection of a point across the y-axis changes the sign of the x-coordinate while keeping the y-coordinate the same.
Therefore, the reflected coordinates of point K (6,3) would be (-6,3).
So, the correct answer is: (−6,3)
