If a translation of T(2, -7) is applied to ΔABC, then the coordinates of B' is (3, -12).
<h3>What are coordinates?</h3>
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
Given the coordinate of B are (1, -5), also given the rule for the translation T that is (2, -7). Therefore, the translation of the point B will be,
B' = (1+2, -5-7) = (3, -12)
Hence, If a translation of T(2, -7) is applied to ΔABC, then the coordinates of B' is (3, -12).
