27502--.3The triangle is rotated 90° clockwise about the origin.The coordinates of the points in the image are:AYВ'tС.Blank 1:Blank 2:Blank 3:Blank 4:Blank 5:Blank 6:

Okay, here we have this:
When we rotate a point 90° clockwise we obtain this transformation:
(x,y)-->(y,-x)
So, in this case we obtain that
A(-1,3)--->A'(3,1)
B(2,1)--->B'(1,-2)
C(-1,0)--->C'(0,1)
Finally we get that the new points are: A'(3,1), B'(1,-2) and C'(0,1)
