#### Answer

The graph obtained is as shown below:

#### Work Step by Step

The two points which are selected for the calculation of the slope are \[\left( {{x}_{1}},{{y}_{1}} \right)=\left( 1.06,2.81 \right)\]and\[\left( {{x}_{2}},{{y}_{2}} \right)=\left( 1.7,0.89 \right)\].
Now, the slope of a line using the two points is calculated as follows:
\[\begin{align}
& m=\frac{{{y}_{1}}-{{y}_{2}}}{{{x}_{1}}-{{x}_{2}}} \\
& =\frac{2.81-0.89}{1.06-1.7} \\
& =\frac{1.92}{-0.64} \\
& =-3
\end{align}\]
The equation of the line is given in the slope-intercept form.
From that equation, the slope of the line is -3. Also, the slope of the line calculated using the two points in the line is -3.
