The coordinates of the point J' is (1,2)
Explanation:
Given that the point J(-2,1) is rotated about 270° about the origin.
Coordinates of the resulting point J':
Since, we know that, when rotating a point 270° counterclockwise about the origin, the point (x,y) becomes (y,-x) which means we switch the places of x and y coordinates and make x as negative.
Therefore, the transformation is given by
[tex](x,y)\implies (y,-x)[/tex]
Using the above transformation, we have,
(-2,1) ⇒ (1,-(-2)) ⇒ (1,2)
Therefore, the resulting point of the coordinates of the point J' is (1,2)
Answer:
(1,2)
Step-by-step explanation:
(1,2)
270° anticlockwise rotation is the same as 90° clockwise rotation
Which maps:
(x,y) ---> (y,-x)
