Complete Question

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 [tex]y = -\frac{1}{4}x + 40[/tex]

Step-by-step explanation:

Generally a linear equation is mathematically represented as

       [tex]y = mx+c[/tex]

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

             [tex]s = \frac{30 -20}{80 -40}[/tex]

             [tex]s = \frac{1}{4}[/tex]

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

        [tex]s =-\frac{1}{4}[/tex]

The intercept is  40 as seen from the graph

So the linear equation is

        [tex]y = -\frac{1}{4}x + 40[/tex]
