question

Read the following description of a relationship:

Pam loves rock climbing. She has scaled

peaks so far, and she plans to climb another peak each year.

Let

represent the number of years from now and

represent the total number of peaks Pam will have climbed.

This relationship can also be shown in a table. Complete the equation that represents the relationship between

and

y	p
3	12
4	13
5	14
6	15

solution

Read the description of the relationship between the number of years from now,

and the total number of peaks Pam will have climbed,

Pam loves rock climbing. She has scaled 9 peaks so far, and she plans to climb another peak each year.

In this relationship,

is the input, and

is the output. So, you can find

by adding 9 to

Express this relationship as an equation.

You can use the table to check your answer.

y	p
3	12
4	13
5	14
6	15

In each row of the table, plug the value from the

column into the equation. See if you get the value in the

column.

y	y + 9	p
3	3 + 9 = 12	12
4	4 + 9 = 13	13
5	5 + 9 = 14	14
6	6 + 9 = 15	15

The values in the

column are the same as the values in the

column.

This is the equation for the relationship:
