Question

if point P(4,11) is reflected across the line y=3, what are the coordinates of its reflection?
a- (2,11)
b- (11,4)
c- (4,-11)
d-(4,-5)

Answer 1

The answer is D because x coordinate doesn't change as well as the y just being reflected. it is not c because the line that is reflected across is not at y =0

Answer 2

Answer:

(4,-5) D

Step-by-step explanation:

P is on x=4, so that doesn't change in a reflection. P is 8 units above line y=3. So count down 8 from y=3. You should land on y= -5, making the reflected coordinates (4, -5).
