Answer
A (-5, 5)
Explanation
When the transformation Ta, b is performed on a given coordinate B (x, y), it becomes B' [(x + a). (y + b)]
So, for this question, the transformation is T2, -1, on point A (x, y) to give the image point A' (-3, 4)
A' (-3, 4) = A' [(x + 2), (y - 1)]
x + 2 = -3
x = -3 - 2 = -5
y - 1 = 4
y = 4 + 1 = 5
So, the coordinates of point A is (-5, 5)
Hope this Helps!!!
