Triangle PQR has the following coordinates: P (-9,-12) Q(-6, -13) R(-7, -4)

Where is Q' after a rotation 90° clockwise?

Please write your answer as a coordinate: (x, y)

The coordinates of Q’ are (-13,6)

Step-by-step explanation:

Here, we want to get the coordinates of the point Q’ obtained by rotating point Q at a degree of 90 clockwisely

Generally, we have the formula for the rotation as follows;

(x,y) will then (y,-x)

Thus,

(-6,-13) will become (-13, -(-6)) = (-13,6)

i had a similar work too, kindly contact professor james. so far he has handled 2 online tests and a paper for me. i attained 100% in both tests and 97% on the paper. kindly let him know that i referred you, i’m johnson.
