We have to find the equation of the line that represents the demand function.
The first step is to find the slope of the line, using the given pair of values.
[tex]m=\frac{8.45-9.95}{95-80}=-0.1[/tex]
Now, use the point slope formula to find the equation of the line:
[tex]\begin{gathered} p-8.45=-0.1(q-95) \\ p=-0.1q+9.5+8.45 \\ p=-0.1q+17.95 \end{gathered}[/tex]
It means that the answer is p=-0.1q+17.95.
