Atriangle is located on a three-dimensional coordinate plane. Matrix Ashows the location of each vertex, where the first column
represents the x coordinate, the second column represents the y coordinate, and the third column represents the coordinate
The triangle is dilated by a scale factor of 2, then translated by the factors in matrix B, resulting in an image triangle as
represented by the equation below.
2A-90
in which directions are the vertices translated, as indicated by matrix B?
