(a) The vector 7= (4) is rotated through an angle of 45° about the origin O(0, 0). Use the appropriate transformation matrix to calculate the result of this transformation. (b) The point (2, 3) is reflected over the straight line y = 3x. Use the appropriate transformation matrix to calculate where the point is reflected to. (c) The point (4, —2) is reflected over the y-axis. Use the appropriate transformation matrix to calculate where the point is reflected to.
