The goal of the game is to earn power points by defeating goblins. Today, Brendandefeats 1 goblin and earned 3 power points. Meg defeats 3 goblins and earns 9 power points.In this relationship, x represents the number of goblins defeated, and y represents thenumber of power points earned.Graph two points for this relationship and the line passing through them.Standard

Answer 1

Yes, x and y have a proportional relationship.

Kindly check the graph below.

1) Graphically speaking every linear proportional relationship has a line crossing the origin, i.e. (0,0).

2) Let's plot the given points according to the text. As we can see, the horizontal axis is labeled as the number of goblins defeated while the vertical axis, the number of power points;

If we examine carefully the points, we can see that the y-coordinate is the triple of the x-coordinate. So, we can infer that to be y=3x;

3) Yes, this is a Proportional relationship.
