Given : The equation F=9/5C+32 relates temperature measured in degrees Celsius, , to degrees Fahrenheit, .
To Find : Whether there is a proportional relationship between
Solution:
proportional relationships
y ∝ x
=> y = kx
Comparing with line line of equation
y = mx + c
m = k , c = 0
Hence graph of a proportional relationship must pa ss through (0, 0)
F=9/5C+ 32
C = 0
=> F = 32
Hence Does not pa ss through ( 0 ,0)
so The equation F=9/5C+32 is not a proportional relationship but a linear relationship
