\[ C=\frac{5}{9}(F-32) \] The equation above shows how temperature \( F \), measured in degrees Fahrenheit, relates to a temperature \( C \), measured in degrees Celsius. Based on the equation, which of the following must be true? I. A temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of \( \frac{5}{9} \) degree Celsius. II. A temperature increase of 1 degree Celsius is equivalent to a temperature increase of 1.8 degrees Fahrenheit. III. A temperature increase of \( \frac{5}{9} \) degree Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.

Solve the system of equations by graphing, (If there is no solution, enter NO sOLUTION, If there are infinitely many solutions, enter INFINITELY MANY.) \[ \begin{array}{l}y=2 x-6 \\ y=-5 x+1\end{array} \] \( (x, y)=(\square \)
