$\"\"$

The table presents a relation.

Write the ordered pairs.

Ordered pairs are $\"\"$ and $\"\"$ .

Graph:

Plot the ordered pairs.

$\"\"$

Then reverse the $\"\"$ -coordinate and the $\"\"$ -coordinate in each ordered pair.

Reversed ordered pairs are $\"\"$ and $\"\"$ .

Graph:

Plot the ordered pairs.

$\"\"$

Find the relationship between the two sets of ordered pairs:

Graph:

Plot the ordered pairs and reversed ordered pairs

Graph the line $\"\"$ .

$\"\"$

Observe the graph:

Each point in the original relation is the same distance from the line as the corresponding point of the reverse relation.

The points are symmetric about the line $\"\"$ .

$\"\"$

Ordered pairs are $\"\"$ and $\"\"$ .

$\"\"$

Reversed ordered pairs are $\"\"$ and $\"\"$ .

$\"\"$

Relationship between the two sets of ordered pairs

$\"\"$

The points are symmetric about the line $\"\"$ .
