question

Complete the table and write the equation for the relationship shown in the graph.

x	y
0
1	5
2	10
4	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 first row.

x	y
0	?
1	5
2	10
4	20

To find the

-value

when the

-value

is 0, find the point on the line with an

-coordinate

of 0.

The point

(

)

is on the line and has an

-coordinate

of 0. Its

-coordinate

is 0.

x	y
0	0
1	5
2	10
4	20

For each row of the table, the number in the

column is a multiple of the number in the

column.

x	y
0	0 5 = 0
1	1 5 = 5
2	2 5 = 10
4	4 5 = 20

In each row of the table, the number in the

column is 5 times the number in the

column. You can write the equation as:
