The y-coordinate of B' after the translation is -6
<h3>How to determine the y-coordinate of B'?</h3>
From the graph, the coordinate of B is given as:
B = (1,2)
The translation 
means:
(x,y) ⇒ (x - 3, y - 8)
So, we have:
B' = (1 - 3, 2 - 8)
Evaluate the difference
B' = (-2, -6)
Remove the x-coordinate
B' = -6
Hence, the y-coordinate of B' is -6
