question

This rule and table describe a relationship between x and

To find

subtract 3 from

x	y
3	0
4	1
5	2
6	3

Which graph shows this relationship?

key idea

Each row in a table of

and

y-values

represents an ordered pair.

An ordered pair

(x,

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

The
x-coordinate

(x-value)
tells you the horizontal position.
The
y-coordinate

(y-value)
tells you the vertical position.

solution

The graph that shows this relationship must have ordered pairs that follow the rule:

To find

subtract 3 from

Each row in the table of

and

y-values

represents one of these ordered pairs. Write the ordered pairs in a new column.

x	y	(x, y)
3	0	(3, 0)
4	1	(4, 1)
5	2	(5, 2)
6	3	(6, 3)

Plot a point for each ordered pair.

Now draw a line through these points. The line represents all ordered pairs that follow the rule.
