How is -2 degrees Celsius expressed in Fahrenheit?

To convert degrees Celsius to Fahrenheit, you can use the formula:

[ F = \frac{9}{5}C + 32 ]

In this case, substituting -2 for C:

[ F = \frac{9}{5}(-2) + 32 ]

First, calculate (\frac{9}{5} \times -2):

[ \frac{9 \times -2}{5} = \frac{-18}{5} = -3.6 ]

Next, add 32 to -3.6:

[ -3.6 + 32 = 28.4 ]

Thus, -2 degrees Celsius is equal to 28.4 degrees Fahrenheit. This aligns with the correct answer, which reflects the accurate calculation performed using the conversion formula. The other choices do not correspond to the correct calculation, as they yield temperatures that do not convert correctly from -2 degrees Celsius within the bounds of the formula provided.
