What is the y-coordinate of B′ ?

Enter your answer in the box.

Answer 1

The answer is 6. i just did the quiz 

Answer 2

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position. The y-coordinate of point B′ will be 6.

What are coordinates?

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

Given the coordinates of the point B as (6, -3). Also, the rule through which point B is needed to translate as (x−5, y+9). Therefore, the new coordinates of point B after translation will be,

Point B' → (6 - 5, -3 + 9) → (1, 6)

Therefore, the new coordinates of point B are B' (1, 6).

Hence, the y-coordinate of point B′ will be 6.
