Answer:
The rule would rotate the figute 270° clockwise is: (x,y)→(-y,x)
The coordinate would be the output for point A' is (4,0)
Step-by-step explanation:
When you make a rotation of 270° clockwise of a point P=(x,y), the coordinates of the new point will be P'=(-y,x). Then, the rule would rotate the figue is (x,y)→(-y,x)
In this case the point:
A=(0,-4)=(xa,ya); xa=0, ya=-4
The output would be:
A'=(-ya,xa)=(-(-4),0)→A'=(4,0)
