question

Jack has 5 shells in his seashell collection. He is going to the beach next week, so he plans to collect some more.

The rule for this pattern is t = s + 5, where s is the number of seashells he will collect and t is the total number of seashells he will have.

Graph 3 points that follow the rule.

solution

You need to graph 3 points that follow the rule

where s is the number of seashells Jack will collect and t is the total number of seashells he will have.

Start by making an input/output table. You can use 1, 2, and 3 as your inputs. The rule is

so add 5 to each input to get the output.

Input (s)	Output (t)
1	1 + 5 = 6
2	2 + 5 = 7
3	3 + 5 = 8

Use the input/output table to write ordered pairs of numbers. In each pair, write the input first and the output second.

(
1
,
6
)
(
2
,
7
)
(
3
,
8
)

Now, graph your pairs. Start with the first pair,

(

)

You can plot the other pairs the same way. This graph shows 3 points that follow the rule
