Question

1. interchange the ( x )- and ( y )-values of each ordered pair.

Explanation:

Step1: Swap x and y values

For an ordered pair $(x,y)$, the new pair is $(y,x)$.

Step2: Apply to (-1,-1)

$(-1,-1) \to (-1,-1)$

Step3: Apply to (0,0)

$(0,0) \to (0,0)$

Step4: Apply to (1,1)

$(1,1) \to (1,1)$

Step5: Apply to (8,2)

$(8,2) \to (2,8)$

Answer:

$(-1,-1) \to (-1,-1)$
$(0,0) \to (0,0)$
$(1,1) \to (1,1)$
$(8,2) \to (2,8)$
