Scarlet and Mason are trying to
find the coordinates of the image four, nine after a reflection over the
š„-axis. Scarletās answer was four, negative
nine while Masonās answer was negative four, nine. Which of them is correct?

Hereās what we know about
coordinates. We have our š„-axis and our
š¦-axis. Quadrant one represents positive,
positive. Quadrant two has coordinates with a
negative š„ and a positive š¦. In quadrant three, both the š„- and
š¦-axis values are negative. And in quadrant four, we have a
positive š„ value and a negative š¦ value.

Our image is a positive and a
positive and would fall in the first quadrant. If this image is reflected over the
š„-axis, it will be reflected down into the fourth quadrant. It would be positive four, negative
nine. And that is reflected in Scarletās
answer.

Scarlet answered correctly by
saying that the reflected image would be located at four, negative nine.
