Question

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

Answer 1

the x-coordinate is negative, and the y-coordinate is negative

Explanation:

the guy above said so?

Answer 2

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

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''
