Answer 2

So we use the form

`y = mx + b`
Find b by looking at the start point, in this case: 110. So we have:

`y = mx + 110`
Then, we see that it is a decreasing line, so we know that m < 0.
Filling in

`x = 20`
Gives y = 70, so solve the (function) equation:

`f(20) = 70`

`20 * m + 110 = 70`

`20m + 110 = 70`

`20m = - 40`

`m = - 2`
Therefore the formula is:

`n = - 2m + 110`
Or:
N = -2M+110 as I couldn't find capital letters :-(
