Question

Identify the reflection of the figure with vertices P (2, −12), Q (−3, 13), and R (−5, −15) across the x-axis.
P (−2, −12), Q (3, 13), R (5, −15)
P (2, 12), Q (−3, −13), R (−5, 15)
P (−12, 2), Q (13, −3), R (−15, −5)
P (12, 2), Q (−13, −3), R (15, −5)

Answer 1

reflections across the x-axis  leaves the x  coordinates the same but the y coordinates  change sign

so point P (2,-12) is reflected to (2, 12)
So now you can identify the correct choice

Answer 2

If the ordinate is positive then after reflection it becomes negative and vice-versa. Then the coordinates will be P(2, 12), Q(−3, −13), and R(−5, 15). Then the correct option is B.

What is a reflection of the point?

It is the image of the point which is located in the opposite direction of a given point.

Identify the reflection of the figure with vertices P (2, −12), Q (−3, 13), and R (−5, −15) across the x-axis.

If the ordinate is positive then after reflection it becomes negative and vice-versa.

 P (2, −12) ⇒ P(2, 12)

Q (−3, 13) ⇒ Q(−3, −13)

R (−5, −15) ⇒ R(−5, 15)
