Question

Triangle ABC has coordinates of A(–6, –7), B(4, –2), and C(0, 7). Find the coordinates of its image after a dilation centered at the origin with a scale factor of 2.

A(–3, –3.5), B(2, –1), C(0, 3.5)
A(–12, –7), B(8, –2), C(0, 7)
A(–12, –14), B(8, –4), C(0, 14)
A(–6, –7), B(4, –2), C(0, 7)
