The temperature , in degrees Celsius, inside a specialized freezer minutes after it is unplugged is given by the equation . If this equation is graphed in the -plane, which of the following is the best interpretation of the -coordinate of the line's -intercept in the context of the problem?
The initial temperature inside the freezer, in degrees Celsius
The rate at which the temperature inside the freezer increases, in degrees Celsius per minute
The number of minutes it takes for the temperature inside the freezer to reach 0 degrees Celsius
The total change in temperature inside the freezer, in degrees Celsius, from the moment it was unplugged until it reached 0 degrees Celsius
