The y-coordinate of B' after the translation is -6
How to determine the y-coordinate of B'?
From the graph, the coordinate of B is given as:
B = (1,2)
The translation [tex]T_{-3,-8}(x,y)[/tex] 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
