Question

Graph image of rectangle JKLMN there a rotation of 90 counter clockwise about the origin

Answer 1

ANSWER

EXPLANATION

The rule to rotate a point (x, y) 90° counterclockwise about the origin is,

$(x,y)\to(-y,x)$

To draw the image of this rectangle, rotate each of the vertices,

$\begin{cases}J(1,5)\to J^{\prime}(-5,1) \\ K(3,5)\to K^{\prime}(-5,3) \\ L(3,2)\to L^{\prime}(-2,3) \\ M(1,2)\to M^{\prime}(-2,1)\end{cases}$

Graph the new vertices and draw the rectangle,
