Corrine wrote temperatures in degrees Celsius and the equivalent temperatures in degrees Fahrenheit. Equivalent Temperatures Celsius negative 10 5 10 20 Fahrenheit 14 41 50 68 Which explains how Corrine could determine if the temperatures vary directly?
Answer
A
Draw a graph of the temperatures; if the points form a straight line, then the temperatures vary directly.
B
Look for a pattern in the table; if the pattern is consistent, then the temperatures vary directly.
C
Compare the equivalent temperatures as a ratio; if the ratios are equivalent, then the temperatures vary directly.
D
Write an equation that converts one temperature to another; if the temperatures satisfy the equation, then they vary directly.
