Determine What Signs on Values of X and Y Would $\mathrm { T } = 0.117 \mathrm { x } + 87.16$

Determine what signs on values of x and y would make the statement true. Assume that x and y are not 0.
-As the relative humidity increases, the temperature seems higher than it is. The formula $\mathrm { T } = 0.117 \mathrm { x } + 87.16$ approximates the apparent temperature for an actual temperature of $95 ^ { \circ } \mathrm { F }$ , where $x$ is the relative humidity. What is the apparent temperature (to the nearest degree) for a relative humidity of $100 \%$ ?

A) $99 ^ { \circ } \mathrm { F }$
B) $1020 ^ { \circ } \mathrm { F }$
C) $87 ^ { \circ } \mathrm { F }$
D) $187 ^ { \circ } \mathrm { F }$
