By which matrix should you multiply vector [1 3] to rotate it 180°?

We have that the Rotation of matrix will be rotated 180 degree if is multiplied by  

Option D is correct

From the Question we are given

it is important to note that the rotation of the identity matrix   rotating across the Cartesian co-ordinate is a is going to give a matrix    

Therefore

The Rotation of matrix will be rotated 180 degree if is multiplied by  

Option D is correct

B

Step-by-step explanation:

Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.
