Exercise 4 Page 225

To graph the polygon, let's plot the given vertices and then connect them.

When a figure is rotated $90^{\circ }$ counterclockwise about the origin, the coordinates of the image's vertices will change in the following way. Let's find the coordinates of the image according to the rule.

$(a,b)$	$(\text{-}b,a)$
$J(\text{-}1,1)$	$J^{\prime }(\text{-}1,\text{-}1)$
$K(3,3)$	$K^{\prime }(\text{-}3,3)$
$L(4,\text{-}3)$	$L^{\prime }(3,4)$
$M(0,\text{-}2)$	$M^{\prime }(2,0)$

Finally, we can plot the image $J^{\prime }{K}^{\prime }{L}^{\prime }{M}^{\prime }$
