Answer:
converts Celsius to Fahrenheit.
converts Fahrenheit to Celsius.
Step-by-step explanation:
Write given data in the table

Let the expression for the function be

Note, that this equation is linear equation and it is well-known fact that the Celsius to Fahrenheit dependence is linear.
Substitute corresponding values into this expression:

Subtract these two equations:

Substitute it into the first equation:

So,

This is the function which converts Celsius to Fahrenheit.
And function
converts Fahrenheit to Celsius.
To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6 /-5x (subtract 5x both sides)
3y=-5x+6 /:3 (divide both sides by 3)
y=

In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=

and its the result
