\

From the information, write the degree of Celsius as x - coordinate and the degree of Fahrenheit as y - coordinate.

\

From the information, the points are $\"\"$ .

\

Substitute the values of $\"\"$ in the slope formula $\"\"$ .

\

$\"\"$ . $\"\"$

\

To write the line equation, we can use either of the two given points.

\

Consider the point (0, 32).

\

Substitute $\"\"$ in point-slope form equation or $\"\"$ .

\

$\"\"$

\

Add 32 to each side.

\

$\"\"$

\

$\"\"$ .

\

The slope $\"\"$ and y - intercept $\"\"$ . $\"\"$

\

The line equation is $\"\"$ .

\

The temperature is the same on both scales, so $\"\"$ .

\

Substitute the value of $\"\"$ in the above equation.

\

$\"\"$

\

Subtract $\"\"$ from each side.

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

$\"\"$

\

Multiply each side by $\"\"$ .

\

$\"\"$

\

Cancel common terms.

\

$\"\"$ . $\"\"$

\

The value of temperature is the same on both scales is $\"\"$ .
