<u>Using the ratio to find x:</u>
test? is it? if it is i can't tell you
Answer: 7
5+7+9=21
3 total numbers to start with so;
21/3=7
D = (13, - 23 )
Given the translation rule
(x, y ) → (x - 4, y + 15 )
To go in the reverse direction, that is image to original, then, reverse the operations in the translation rule.
(x , y ) → (x + 4, y - 15 ) , thus
D'(9, - 8 ) → D(9 + 4, - 8 - 15 ) → D(13, - 23 )
