Which explains how Corrine could determine if the temperatures vary directly?
a ratio; if the ratios are equivalent, then the temperatures vary directly.
O Compare the equivalent temperatures as
O Draw graph of the temperatures; if the points form straight line, then the temperatures vary directly.
O Write an equation that converts one temperature to another; if the temperatures satisty the equation, then they vary
directly.
O Look for a pattern in the table; if the pattern is consistent, then the temperatures vary directly.
