question

Eva is playing a video game. Every time she finds a secret passageway, she gets 2 treasure maps.

The rule for this pattern is

where p is the number of secret passageways she finds and m is the number of treasure maps she has.

Graph 3 points that follow the rule.

solution

You need to graph 3 points that follow the rule

where p is the number of secret passageways Eva finds and m is the number of treasure maps she has.

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

so multiply each input by 2 to get the output.

Input (p)	Output (m)
1	1 2 = 2
2	2 2 = 4
3	3 2 = 6

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

(
1
,
2
)
(
2
,
4
)
(
3
,
6
)

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
