Exercise 1 Page 271

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

{(- 15,4), (- 18,- 8), (- 16.5, - 2), (- 15.25,3)}

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, - 15) ( - 15, 4)
( -8, - 18) ( - 18, - 8)
( -2, - 16.5) ( - 16.5, -2)
( 3, - 15.25) ( - 15.25, 3)

Let's write the inverse relation as a data set. {(- 15,4), (- 18,- 8), (- 16.5, - 2), (- 15.25,3)}
