Ответ:
(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) ..
