5	20

key idea

Each row in a table of

and

-values

represents an ordered pair.

An ordered pair

(

)

tells you the location of a point on the coordinate plane.

The
x
-coordinate
tells you the horizontal position.
The
y
-coordinate
tells you the vertical position.

Each row of the table represents a point on the line in the graph. Use the graph to find the missing value in the table.

Look at the third row.

x	y
1	4
3	12
4	?
5	20

To find the

-value

when the

-value

is 4, find the point on the line with an

-coordinate

of 4.

The point

(

)

is on the line and has an

-coordinate

of 4. Its

-coordinate

is 16.

x	y

3	12
4	16
5	20

For each row of the table, the number in the

column is a multiple of the number in the

column.

x	y
1	1 4 = 4
3	3 4 = 12
4	4 4 = 16
5	5 4 = 20

In each row of the table, the number in the

column is 4 times the number in the

column. You can write the equation as:
