Answer:
the third option (x,y) -> (-x, -y+5)
Step-by-step explanation:
just look at the x coordinate of B, and see what it became as x coordinate of B'.
Bx = -2
B'x = 2
same for the other points.
so, we need a solution with a "-" sign for x.
and the third answer option is the only one that has that.
just to check - it also fits the y values.
By = 2
B'y = -By +5 = -2 + 5 = 3
and that's what the graph shows.
and so on - we can do this with all the points.
but we have proven already what the correct answer is.
