Why do you think it might be useful to rearrange formulas before solving for one of the variables? (Relate your answer to the Celsius and Fahrenheit formulas and examples.)

It makes the solution of the equation easier

Step-by-step explanation:

Here we have the formula relating Celsius and Fahrenheit given as follows;

From the above Celsius to Fahrenheit equation, we have that to solve for F we rearrange the formula as follows

Which is the same as

It is then seen that rearranging the equation between Celsius and Fahrenheit makes it easier to solve for either °C or °F.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
