Question

Point (5,-3) is rotated about 90 degrees counterclockwise what are the coordinates of point A

Answer 1

(5,-3) is in the fourth quadrant, if it rotates 90 counter clockwise then it will be in the first quadrant. Your x and y values are going to swap, and you need to know what is true about the numbers since they are in the first quadrant. leave a comment if you need more help.

Answer 2

The co-ordinate of point A after rotated about 90 degrees counterclockwise is (3,5)

We have to determine, the point of A after point (5,-3) is rotated about 90 degrees counterclockwise.

To find the co-ordinate of point A after 90 degrees rotation counterclockwise following all the steps given below.

• Step1; Point (5,-3) is rotated about 90 degrees counterclockwise. so, the rule that applies here is,

        $(x,y) = (-y,x)$

• Step2; Based on the rule given in the step we have to find point A.

                    $(5,-3) = (3,5)$

• Step3; The points rotated about 90 degrees is in 1st quadrant,

                  $(3,5)$

Hence, The co-ordinate of point A after rotated about 90 degrees counterclockwise is (3,5)
