Step 1
If we have 2 points (x0, y0) and (x1, y1) then the point-slope form is yy1=m(xx1), here, m is the slope given by:
m=y1y0x1x0
Hence, the point-slope form becomes yy1=(y1y0x1x0)(xx1)
Now, we have to find the relation between Fahrenheit and Celcius.
Let Fahrenheit be represented by F and Celcius by C.
Now, we are given that 100C=212F and 0C=32F
This means that when the temperature is 100C then it is same as 212F, and when the temperature is 0C it is same as 32F
Therefore, let:
C0=0C and F0=32F
C1=100C and F1=212F
Step 2
Therefore, we receive two points
(C0, F0)=(0, 32)
(C1, F1)=(100, 212)
Now, we find the point-slope form:
FF1=(F1F0C1C0)(CC1)
F212=(212321000)(C100)
F212=(180100)(C100)
F212=(95)(C100)
F212=95C(95)100
F212=95C9×20
F212=95C180
F=95C+32

Step 1
The relatijn between the celsium and Fanrenhcit scals
As the temperature risce on the celsius scale the equivalent temperature of fahrenhcit waild also be high
As the temperature falls on the celsius scale, the temp equal to fahrenhciet would also be low-
freezing point of water at {}C=0C
and boiling point of untered {}C=100C
freezing point of water at Fahrenhcit =32F
Boiling point
According to thed
CL×F×PU×F×PL×F×P=FL×F×PU×F×PL×F×P
L×F×P=Lower Fixed point
U×F×P=Upper fixed point
CO1000=F3221232
C100=F32180
C5=(F32)9
C=59(F32)
C=59F5×329
c=59F1609

Step 1
If C is a function, then we may represent the points as (F, C)
(CC1)=m(FF1)
(32,0)
(212.100)
(C0)=100021232(F32)
C=100180(F32)
C=59(F32)
