ABC has coordinates of A(–5, –7), B(6, –3), and C(2, 7). Find the coordinates of its image after a dilation centered at the origin with a scale factor of 2.
(A)A(–5, –7), B(6, –3), C(2, 7)
(B)A(–2.5, –3.5), B(3, –1.5), C(1, 3.5)
(C)A(–10, –14), B(12, –6), C(4, 14)
(D)A(–10, –7), B(12, –3), C(4, 7)

You are simply doubling each coordinate

jim_thompson5910 · Answer

So A(-5,-7) becomes A ' (-10, -14) because you would double -5 to get -5*2 = -10 and double -7 to get -7*2 = -14

jim_thompson5910 · Answer

you do the same for each of the remaining points B and C
