Consider triangles JKL and J′K′L′, with J(−10,1), K(−12,5), L(−5,4), J′(−30,3), K′(−36,15), and L′(−15,12).

A: What is the scale factor, k, for the dilation that takes △JKL to △J′K′L′?
B: What is the mapping statement for this dilation?

Select two answer choices: one for Question A, and one for Question B.

A: k=−3
B: (x, y)↦(−3x,−3y)
A: k=13
A: k=3
B: (x, y)↦(3x,3y)
B: (x, y)↦(13x,13y)
