Answer:
The x-coordinate is negative, and the y-coordinate is negative.
Step-by-step explanation:
It's a bite hard to explain it without a xy-plane. I don't want to upload it, so I will try to draw it:
[tex]\left[\begin{array}{ccc}a&|&b\\-&-&>\\c&|&d\end{array}\right][/tex]
We have point [tex]a[/tex] in the coordinates [tex](-x, y)[/tex]
We have point [tex]b[/tex] in the coordinates [tex](x, y)[/tex]
We have point [tex]c[/tex] in the coordinates [tex](-x, -y)[/tex]
We have point [tex]d[/tex] in the coordinates [tex](x, -y)[/tex]
A point with a positive x-coordinate and a negative y-coordinate is reflected over the y-axis.
This point is [tex]d[/tex]. Once it is reflected over the y-axis, it turns to be point [tex]c[/tex].
