#### Answer

Independent variables: Values of Temperature Dependent variables: Values of Velocity Relationship: The relationship is between the velocity of sound in different temperatures. We can see that as the values of temperature get higher, the velocity of sound is faster to so we can conclude that the higher the temperature, the faster the sound waves will be moving The equation is: y=$\frac{3}{5}x$+331

#### Work Step by Step

After looking at the graph, we can say that as temperature increases, the velocity of the sound increases as well.
