Point G’ has coordinates (- 5, 2) If it was reflected across the y-axis, what were the coordinates of its pre image?

a.) (- 5, - 2)
b.) (5,2 )
c.) (2, - 5)
d.) (5, - 2)

b. 5, 2

Step-by-step explanation: got it right :p

been looking for the answer havent been able to find it   but good luck with it

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
