Exercise 1 Page 396

To find the inverse of a relation written as coordinate pairs, we exchange the x- and y-coordinates of each ordered pair.

Given Point	Inverse Point
( - 9, 10)	( 10, - 9)
( 1, - 3)	( - 3, 1)
( 8, - 5)	( - 5, 8)

Let's write the inverse relation as a data set. {(10, - 9), (- 3, 1), (- 5, 8)}
