If parallelogram jklm is rotated 270° counterclockwise around the origin, what are the coordinates of the endpoints of the side congruent to side kl in the image parallelogram? a. k’(-4, -6); l’(3, -3) b. k’(6, 4); l’(3, 3) c. k’(-6, -4); l’(-3, -3) d. k’(-4, 6); l’(-3, -3)

The correct answer is:

B) K’(6, 4); L’(3, 3)

Explanation:

A 270° clockwise rotation maps every point (x, y) to (y, -x). (It negates the x-coordinate and then switches it and the y-coordinate.)

This means the endpoints of the side congruent to KL, K' and L', would be mapped as:

K'(-4, 6)→(6, 4)

L'(-3, 3)→(3, 3)

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
