Answer:
The sentence that describes the reflected point (x,-y) over the y-axis is:
<em>''a point with a negative x-coordinate and a negative y-coordinate'' </em>
Step-by-step explanation:
<em>Since not sure if specific options are available lets answer this question in a general notation. </em>
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).
<u>Therefore the new reflected point will now be:</u>
which in sentence form can read as:
<em>''a point with a negative x-coordinate and a negative y-coordinate'' </em>
