Exercise 6 Page 553

We are given three vertices of △ JKL. To graph the triangle, let's plot the points and then connect them.

To find the images of the points reflected in the y-axis, we can use the coordinate rule. Two points reflected in the y-axis have opposite x-coordinates.

(a,b)	(- a, b)
J(1,3)	J'( -1,3)
K(4,4)	K'( -4,4)
L(3,1)	L'( -3,1)

Now we can graph the image of △ JKL after a reflection in the y-axis.
