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(–4, –2), B(4.67, –4.67), C(0, 2)
A(–6, –3), B(7, –7), C(0, 3)
A(–9, –4.5), B(10.5, –10.5), C(0, 4.5)
A(–9, –3), B(10.5, –7), C(0, 3)
