Question

The equation F= 9/5C +32 relates temperature measured in degrees Celsius. C, to degrees Fahrenheit, F. Determine whether there is a proportional relationship between C and F.

Answer 1

korrect

Explanation:

it looks right

Answer 2

Given:

The equation is

`F=(9)/(5)C+32`

To find:

Whether there is a proportional relationship between C and F.

Solution:

If there is a proportional relationship between C and F, then the line of given equation passes through (0,0) and the equation must be true for (0,0).

Put F=0 and C=0 in the given equation.

`0=(9)/(5)(0)+32`

`0=0+32`

`0=32`

This statement is not true because
`0\\eq 32`.

It means the line of given equation does not passes through (0,0). So, it s not a proportional relationship.

Hence, there is not a proportional relationship between C and F.
