Corrine wrote temperatures in degrees Celsius and the equivalent temperatures in degrees Fahrenheit. Equivalent Temperatures
Celsius
–10
5
10
20
Fahrenheit
14
41
50
68

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

The correct answer is option B

"Draw a graph of the temperatures; if the graph form a straight line, then the temperature vary directly."

For any linear equation, the points can only be varying directly and hence all points  would lie on the same line. This simply means, as one variable changes to another value, then the other variable also changes in the same ratio (even though its a higher or lesser value).
