Question

Which coordinate Gird shows the correct locations of P (1,2.5) Point Q which is a reflection Of point P across the Y-axis And R (2.-2.5)

Answer 1

The first thing we are going to do is define point Q
"Point Q which is a reflection Of point P across the Y-axis"
Therefore, we have:
Q = (-1, 2.5)
Now we graph each ordered pair.
