Exercise 8 Page 267

Exchange the x- and y-coordinates in each ordered pair.

{(13,- 5), (10.8,6), (11.4,3), (14,- 10)}

Practice makes perfect

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
( - 5, 13)	( 13, - 5)
( 6, 10.8)	( 10.8, 6)
( 3, 11.4)	( 11.4, 3)
( - 10, 14)	( 14, - 10)

Let's write the inverse relation as a data set. {(13,- 5), (10.8,6), (11.4,3), (14,- 10)}
