Question

Point B(6, −3) is translated using the rule (x−5, y+9).

What is the y-coordinate of B′ ?

Answer 1

Answer: The y coordinate of B' is 6

Step-by-step explanation:

B' is the translation of B where the coordinate of B are (6;-3)

The rule is (y+9) then we added 9 on -3.

Answer 2

Answer:

the y-coordinate of B′ is 6

Step-by-step explanation:

We know that point B(6, -3) where:

x = 6;

y= -3;

if that point is translated to point B' we have to move as the rule given:

(x-5,y+9)

We can now substitute the variables for the values of point B, therefore we get that the new point B' is:

(x-5,y+9) = (6-5 ,-3+9) = (1,6)

So, Point B'(1,6) where the y-coordinate is 6.
