Answer:
The correct answer is the third option (x, y) => (2x - 10, 2y)
Step-by-step explanation:
The points that form the figure ABC are:
A = (2, 7)
B = (1, 2)
C = (3, 4)
If we apply the transformation: (x, y) => (2x - 10, 2y)
Which coincides with the points that form the triangle A'B'C'.
Thus, the correct option is the third one
