Question

rotations
given the coordinates of the pre - image, drag the points to graph the image.
rotate 90° cc
about origin
j(3,2) k(8,1) l(-1,8)
j k l

Explanation:

Step1: Recall 90° CCW rotation rule

For a point \((x, y)\), rotating 90° counterclockwise about the origin transforms it to \((-y, x)\).

Step2: Rotate point J(3,2)

Apply the rule: \(x = 3\), \(y = 2\) → \(J'(-2, 3)\).

Step3: Rotate point K(8,1)

Apply the rule: \(x = 8\), \(y = 1\) → \(K'(-1, 8)\).

Step4: Rotate point L(-1,8)

Apply the rule: \(x = -1\), \(y = 8\) → \(L'(-8, -1)\).

Answer:

To graph the image:

• \(J'\) has coordinates \((-2, 3)\)
• \(K'\) has coordinates \((-1, 8)\)
• \(L'\) has coordinates \((-8, -1)\)

(These points should be dragged to their respective positions on the coordinate grid based on the calculated coordinates.)
