Question

a point with a positive x-coordinate and a negative y-coordinate is reflected over the y-axis. Which sentence describes the coordinates of the new point?

Answer 1

Answer:

The sentence that describes the reflected point (x,-y) over the y-axis is:

''a point with a negative x-coordinate and a negative y-coordinate''

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. $x$ and $y$); where the horizontal line represents the $x$ values and the vertical line representes the $y$ values.

Now we are told that we have a point with a positive x-coordinate and a negative y-coordinate, thus:

$(x,-y)$

This means our point is located at the 4th Quadrant (where $x$ values are positive and $y$ values are negative).

Reflecting it over the y-axis means that our point is now located on the 3rd Quadrant (where both $x$ and $y$ values are negative).

Therefore the new reflected point will now be:

$(-x,-y)$

which in sentence form can read as:

''a point with a negative x-coordinate and a negative y-coordinate''
