Answer: There is a linear relationship between quantity A and quantity B because it produces a straight line.
Step-by-step explanation:
From the given graph we can see there is a straight line.
It implies there is a linear relationship between the quantities.
In linear relationship there is a directly proportionality relation between the quantities which means change in an independent variable will always produce a corresponding change in the dependent variable.
Thus, Quantity B is directly proportional to quantity A.
