Rate brainliest 1. answer the questions by drawing on the coordinate plane below. (2 points possible) (a) draw the image of jkl after a rotation of 90°counterclockwise about the origin. label the image jk l. (b) draw the image of jkl after a reflection across the y-axis. label the image jkl..

Given coordinates of the triangle: J(-4,1), K(-4,-2) and L(-3,-1).

We are given that image is rotated 90° counterclockwise about the origin.

In order to find the new coordinates of rotation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).

Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.

In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.

On applying rule (h, k) ---> (-k,h), we get

Blue image is rotation of 90°counterclockwise about the origin.

2) Rule for reflection about y-axis would be (h, k) ---> (-h,k).

On applying rule (h, k) ---> (-h,k), we get

Red image is reflection across the y-axis.

it would be 6xy and -16xy.
