Question

Which graph or equation represents a nonproportional relationship? A On coordinate plane A, a line goes through points (negative 2, 0) and (0, 1). B On coordinate plane B, a line goes through points (0, 0) and (2, negative 2).

Answer 2

Answer: Option A.

Explanation:

We have two types of linear relationships.

Proportional relationships:

y = a*x

you can see that when x = 0, y also is equal to 0, so these relationships always goes through the point (0,0).

non-proportional relationship.

y = a*x + b.

In this type of relationships, when x = 0 we have:

y = a*0 + b

y = b

So in this case we have the point (0, b). (where b is different than zero)

Then the correct option, for a nonproportional relationship is the option that goes through points (-2, 0) and (0, 1).
