which on these linear equations best describe the given model

The description and diagram of the model is shown on the first uploaded image

Answer:

The linear equation is
`y = -(1)/(4)x + 40`

Explanation:

Generally a linear equation is mathematically represented as

`y = mx+c`

m is the slope which can be obtained from the graph diagram as

`s = (30 -20)/(80 -40)`

`s = (1)/(4)`

Now this slope is a negative slope as seen from the diagram so

`s =-(1)/(4)`

The intercept is 40 as seen from the graph

So the linear equation is

`y = -(1)/(4)x + 40`
