How do you determine if any scatterplot has a positive correlation between the variables

A scatterplot for final lead versus halftime lead is labeled plot A, and the plots are increasing linearly. A scatterplot for final deficit versus halftime deficit is labeled plot B, and the plotted points are increasing linearly.

Does either scatter plot indicate a positive correlation between the variables?

A.
only plot A
B.
only plot B
C.
both plot A and plot B
D.
neither plot A nor plot B
