Question

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?(1 point) Responses (6,−3) left parenthesis 6 comma negative 3 right parenthesis (3,6) left parenthesis 3 comma 6 right parenthesis (−3,6) left parenthesis negative 3 comma 6 right parenthesis (−6,3)

Answer 1

To reflect a point across the y-axis, you change the sign of the x-coordinate while keeping the y-coordinate the same.

For point K with coordinates (6, 3):

• The x-coordinate is 6, and its reflection across the y-axis will be -6.
• The y-coordinate remains the same at 3.

Therefore, the new coordinates of point K after reflection across the y-axis will be (-6, 3).

So, the correct answer is: (−6,3).
