Write the equation that gives the relation between $t_F$ and $t_C$.

(N/A) The relationship between the temperature in Fahrenheit $(t_F)$ and the temperature in Celsius $(t_C)$ is derived from the freezing and boiling points of water on both scales.
On the Celsius scale,the freezing point is $0^\circ C$ and the boiling point is $100^\circ C$.
On the Fahrenheit scale,the freezing point is $32^\circ F$ and the boiling point is $212^\circ F$.
The conversion formula is given by:
$t_F = \frac{9}{5} t_C + 32$.
