Answer:
The coordinates of B become (-4, -3)
Step-by-step explanation:
It wants you to reflect point B about the y-axis, to at first, only the x-value will change. Treat the y-axis like a mirror point, or a rotation point for the image. Each point will keep the same distance from the y-axis along the x-axis. Only now, the points will be in Quadrant II, where the x-values are negative, so the coordinates of point B become (-4, 3).
Now we shift the whole shape down 6 units, which changes the vertical values, which are the y values, so y coordinate reduces by 6, making the final coordinates of point B (-4, -3)
