Answer:
The sentence that describes the reflected point (x,-y) over the y-axis
Step-by-step explanation:
Since not sure if specific options are available lets answer this question in a general notation.
Let us consider the Co-ordinate system in two dimensions (i.e. and ); where the horizontal line represents the values and the vertical line representes the values.Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:
This means our point is located at the 4th Quadrant (where values are positive and values are negative).
Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both and values are negative).
Therefore the new reflected point will now be:
''a point with a negative x-coordinate and a negative y-coordinate''
