Question

AB has endpoints at (20, 10) and (20, - 10). Which of the following graphs illustrates a rotation of AB 270 about the origin?

Answer 1

what the other girl said

Explanation:

Answer 2

" Using notation, rotate the point (3, -5) about the origin 270 degrees.' Since the rule for a 270 degrees rotation is (x, y) → (y, -x), the new point would be (-5, -3) "

AB has endpoints at (20, 10) and (20, - 10).

i.e. coordinates of A are (20,10)

and coordinates of B are (20,-10).

After rotating the line AB 270° about the origin the new coordinates will be:

i.e. A(20,10) is transformed to A'(10,-20)

and B(20,-10) is transformed to B'(-10,-20).

Hence we can represent this transformation with the help of the figure attached to the answer.
