Answer 1

Answer

Option

Explanation

When a coordinate (x, y) is translated by T(a, b), it becomes

[x + a, y + b]

So, for this question,

A (1, 4) will be translated by T(-1, 2), it becomes

(1 - 1, 4 + 2) = (0, 6)

So, D2 means the coordinate is dilated by a factor of 2.

When (x, y) is dilated by a scale factor of k, it becomes (kx, ky)

(0, 6) dilated by a scale factor of 2, becomes

(0×2, 6×2) = (0, 12)

Hope this Helps!!!
