Question

I need help I don't understand this!!

Answer 1

B is 2,2 A is -1,1 c is 2,-1

Answer 2

Because you are dilating by 2, then you multiply 2 for all the points

b(2,2) => b (4,4)
a(0,1) => a (0,2)
c(2,0) => c (4,0)

your new points will be A' (0,2) B' (4,4) and C' (4,0)

hope this helps

just graph it on the graph
