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
