Best ResponseYou've already chosen the best response.0To answer this, they're assuming you'll assume the relationship between the temperatures is linear. You want Fahrenheit to be the 'y' and Celsius to be the 'x'. You know the following: when x = 0, y = 32 > (x_1, y_1) when x = 25, y = 77 > (x_2, y_2) You may now use the twopoint formula for a straight line: \[yy_1=\frac{y_2y_1}{x_2x_1}(xx_1) \rightarrow y32=\frac{7732}{250}(x0)\] that is,\[y32=\frac{45}{25}x \iff y=\frac{9}{5}x+32\]

Best ResponseYou've already chosen the best response.0When the temperature is 40 degrees C, x=40, and so the temp. in F is,\[y=\frac{9}{5}40+32=104 ^oF\]
