<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by

Substituting the coordinates of the point C in the above formula, we get;

Therefore, the coordinates of the point C' is (-1,2)
Answer:
Y = 120
Step-by-step explanation:
Y & X
Y = K(X) where K is constant
given: 72 = K(6)
i.e K = 12
Y = 12(x) is the relationship
Y = 12(10)
Y = 120
