Determine What Signs on Values of X and Y Would $C = \frac { 5 } { 9 } ( F - 32 )$

Determine what signs on values of x and y would make the statement true. Assume that x and y are not 0.
-The formula $C = \frac { 5 } { 9 } ( F - 32 )$ expresses the relationship between Fahrenheit temperature, $F$ , and Celsius temperature, C. Use the formula to convert $86 ^ { \circ } \mathrm { F }$ to its equivalent temperature on the Celsius scale.

A) $97 ^ { \circ } \mathrm { C }$
B) $30 ^ { \circ } \mathrm { C }$
C) $66 ^ { \circ } \mathrm { C }$
