On the grid, draw the image of shape R after the transformation represented by the matrix ( - )).
saveliy_v [14]

Answer:

The given matrix is telling us that we must translate the figure one unit to the right side and one unit downside because the first row states 0 x-units and -1 y-units, the second row states 1 x-unit and 0 y-units.

The transformation of the coordinates would be

(1,-1) to (2, -2)

(2,1) to (3, 0)

(4,1) to (5, 0)

(4,-1) to (5, -2)

The image attached shows the representation of the image.
