Answer:
(5,5)
Step-by-step explanation:
Given that B has coordinates as (3,7) When reflected about a line the new coordinates are (3,5)
This implies that by reflection x coordinate remains the same but y reduced by 2 units.
Apply the same logic for unknown O.
C is reflected to O.
Original coordinates of C are (5,7)
Hence new coordinates i.e. that of O would be
x coordinate same as 5
y coordinate 2 less = 7-2 = 5
COordinates of O are (5,5)
