Image point b'(4, -8) was transformed using the translation (x - 2, y + 3). what were the coordinates of b?
(2, -5)
(6, -5)
(2, -11)
(6, -11)

(6,-11)

Step-by-step explanation:

Given

Point B' = (4,-8)

And the translation formula (x-2, y+3)

In order to get the coordinates of the point before translation, both given points have to be put equivalent.

So, for x-coordinate

x-2 = 4

x= 4+2

x= 6

And for y-coordinate

y+3 = -8

y = -8-3

y=-11

So the old coordinates of old point were (6,-11) ..

step-by-step explanation:

6

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
