Point a (-7,-2) is rotated 270 counterclockwise and then shifted down 3 units. what are to coordinates of k’

K'= (-2, 4)

Step-by-step explanation:

First we are going to rotate our point 270° counterclockwise.

The rule for a 270° counterclockwise rotation is , which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:

Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:

We can conclude that the coordinates of K' are (-2, 4)

a: inscribed angles
