Ans: (6,-13) 

Rationale: 

Simply take your pre-image (point before applying transformation) of point B (4,-5) and apply the transformation to each point. Therefore, (x,y) = (4+2,-5-8) = (6,-13)

Answer:

(6,-13)

Step-by-step explanation:

Given : Triangle ABC is translated according to the rule (x, y) → (x + 2, y – 8).

To Find: If the coordinates of the pre-image of point B are  (4, –5), what are the coordinates of B'?

Solution:

Coordinates of B = (4, –5)

Translation Rule : (x, y) → (x + 2, y – 8)

So, (4,5)=(4+2,-5-8) =(6,-13)

So, B' =(6,-13)

Thus the coordinates of B' is (6,-13)

Hence Option D is correct.

lord [1]
The standard equation of a circle is given by:
(x-a)²+(y-b)²=r²
where:
(a,b) is the center and r is the radius.
Given that (a,b) is (-8,-3) and r=2 units
then the equation of the circle will be:
(x-(-8))²+(y-(-3))²=2²
simplifying the above we get:
(x+8)²+(y+3)²=4
