We take a point p= (x,y) the the result of rotation p 90 clockwise about the origin is a new point p'=(x',y')= (-y, x).
ex:
In the case of p=(1,0) the new point is p'= (0, -1)
so, in your case it will be:
for p=(-2,4) the new point is p'= (4, -(-2))=(4,2)

Hi,

coordinates of Pt(-2,4) under a 90 degree clockwise rotation around the origin?

 Pt(4,2)

 a clockwise rotation from (-2,4) would be (4,2).

here's a picture of what it would look like.
