A. The slope of line A'B' is 6, but A'B' does not pass through o.

B.The slope of line A'B' is 9, and line A'B' passes through o.

C. The slope of line A'B' is 9, but line A'B' does not pass through o.

D. The slope of line A'B' is 3 and line A'B' passes through o.

E. The slope of line A'B' is 3, but line A'B' does not pass through o.

What happens when you dilate (using center point O)?

anonymous · Answer

The object becomes larger.

jim_thompson5910 · Answer

good, the scale factor is 3, so that means

OA' = 3*OA
OB' = 3*OB
