question

Every day after school, Ruben and his sister Bridgette play their favorite video game, Wizarding

Legends.

The goal of the game is to earn power points by defeating goblins. Today, Ruben earns 8 power points defeating 2

goblins.

There is a proportional relationship between the number of goblins defeated,

and the number of power points earned,

Graph this relationship. Select two points to draw a line.

key idea

The graph of a proportional relationship between

and

is a straight line passing through the origin

(

)

solution

To graph the relationship, find two points that satisfy it and draw a line through them.

Since the relationship is proportional, the line passes through the point

(

)

In other words, if Ruben defeats 0 goblins, he earns 0 power points.

To find another point, look for clues in the problem related to

and

y-values.
