Answer:

A, B, and C show linear relationships.

Step-by-step explanation:

For something to have a linear relationship, it CANNOT have an x-value with two different y-values.  

To determine if something has two y-values for one x-value, pass a line (like a pencil) over the graph.  If there are any places where the line crosses the graph twice, the graph you have is not linear.
