\left. \begin{array} { l } { ( 1 ) 215 ^ { \circ } F } \\ { ( 3 ) 329 ^ { \circ } F } \end{array} \right.

Answer»

The rate of degrees m = F/C = 180/100 = 1.8 deg F/deg C between freezing and boiling.

So from the straight line general equation we can write F = m C + b = 1.8 C + 32, where F = 32 = b deg F when C = 0 deg C, the two freezing points.

And there, we've just derived the equation for finding F from C. Using the physics. As it should be learned.

Now you just plug and chug the derived equation. When C = - 183 deg, we have F = 1.8*(-183) + 32 = -297.4 deg F
