My teacher hasn't taught us this yet but it's gonna be on the test. can u explain if u can

I don't like your teacher. not teaching something and putting it on the test. I hope that it is just that you weren't paying attention, or you were absent and not because you had a faulty teacher.

ok so from ABC to A"B"C" is down and to the left and it gets bigger

cross out an options that go up and right (cross out B&C)

it got bigger so the scale factor is not 1/2, it is 2

answer is D

Idon’t know the answer to this
