Abc is reflected across the y-axis and then dilated by a factor of 3 using the point (-1,2) as the center of dilation. what is the transformation of b(5,3)?

The correct option is D.

Step-by-step explanation:

The coordinates of point B are (5,3).

If ABC is reflected across the y-axis, then

The coordinates of point B after reflection are

Then dilated by a factor of 3 using the point (-1,2) as the center of dilation.

The coordinates of point B after reflection and dilation are

The transformation of B(5,3) is B'(-13,5). Therefore the correct option is D.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
