Which graph shows a linear relationship? Select yes or no. For A B C D

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.
