Answer:
The mathematical relationship between variables is :
B. Linear
Explanation:
The graph is:
A diagonal line which starts from the lower left and it goes to the upper right.
Since, the curve is a line.
This means that the relationship between the two variable is a linear relationship.
Also, the graph is a increasing graph since with the increase in the values of one variable the value of the other variable also increases.
Hence, the correct answer is: Option: B Linear
