Exercise 9 Page 267

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

{(- 49,- 4), (35,8), (- 28,- 1), (7,4)}

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
( - 4, - 49)	( - 49, - 4)
( 8, 35)	( 35, 8)
( - 1, - 28)	( - 28, - 1)
( 4, 7)	( 7, 4)

Let's write the inverse relation as a data set. {(- 49,- 4), (35,8), (- 28,- 1), (7,4)}
