F= 9/5 (k - 273) + 32 in order to convert a temperature in kelvin, k, into a temperature of degrees in fahrenheit, f, the equation above can be used. which of the following equations correctly expresses the temperature in kelvin in terms of the temperature in fahrenheit?

For this case we have the following equation:
 F = 9/5 (K - 273) + 32
 We must clear the value of K.
 We have have then:
 F-32 = 9/5 (K - 273)
 (5/9) (F-32) = (K - 273)
 K = (5/9) (F-32) + 273
 
 the temperature in Kelvin in terms of the temperature in Fahrenheit is:
 K = (5/9) (F-32) + 273

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
