What’s the slope? And how to find it .help please!

We can plot the points on a graph, we have;
Let's obtain the slope, we can choose any two points;
I go for (0,8) and (1,6).
The slope is
[tex]\begin{gathered} \frac{y_2-y_1}{x_2-x_1} \\ =\frac{6-8}{1-0} \\ =-2 \end{gathered}[/tex]Therefore, the slope of the relationship is -2
