The answer is b and the reason for that is because for the points you are basically dividing by 2 so it’s dilated by a factor of 2 and it’s reflected across the x-axis because the new shape is not beside it is ontop and if you would have reflected it by the y-axis the new shape would be across is it’s like if you bend the graph hotdog style because the line that’s in the middle is the y-axis it will give a yaxis reflection but if you bend it hamburger style because the line across is xaxis it will give you a xaxis reflection:)) hope I helped
