On planet X, the alien residents use a temperature scale in which they define 0 degrees X to be the melting point of nitrogen and 100 degrees X to be the boiling point of nitrogen.
What temperature difference in X degrees does a temperature change of 1 C degree correspond to?
What temperature in degrees X does water freeze?
What temperture in degrees X does absolute zero correspond to?

195.8 deg C = nitrogen boils
210 deg C = nitrogen melts
so 0 to 100 X is 210 C to 195.6 C
14.4 deg C is 100 X
so
change of 1 deg C is change of 6.94 X
relation is linear
X = k C + b
we already know the slope k = 6.94
X = 6.94 C + b
when C = 210, X = 0
0 = 6.94 (210) + b
b = 1458
so
X = 6.94 C + 1458
before we go any further check boiling point of N2
C = 195.6
X = 6.94 (195.6) + 1458
X = 1358+ 1458 = 100 Yeah!
so now use our formula
X = 6.94 C + 1458
to find X for C = 0 (1458 K obviously)
and for C = 273 
I mean 1458 X , not K, obviously

Thank you SO much!!!
