question

Express the relation below as a graph.

x	y
5	10
10	1
4	5

Click to plot points on the graph. Some of the points have already been plotted for you.

key idea

A relation that is written in a table can also be shown as a graph.

Each row in the table can be shown as a single point on the graph.

solution

Go through the rows in the table one by one.

Start with the first row:

x	y
5	10
10	1
4	5

The

-coordinate

is 5. The

-coordinate

is 10. There is already a point with coordinates

(

)

Next consider the second row:

x	y
5	10
10	1
4	5

The

-coordinate

is 10. The

-coordinate

is 1. Graph a point with coordinates

(

)

Finally, consider the third row:

x	y
5	10
10	1
4	5

The

-coordinate

is 4. The

-coordinate

is 5. There is already a point with coordinates

(

)

Here is the completed graph.
