The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship. The graph shows the linear relationship between y, the temperature in degrees Fahrenheit and x, the temperature in degrees in Celsius from the freezing point of water. What does the y-intercept represent in this scenario?

• The freezing point of water in degrees Fahrenheit.

• The freezing point of water in degrees Celsius.

• The temperature outside in the fall at night.

• The temperature outside in the winter at night.
