Answer:
[tex]\:\mathrm{First\: problem:\:}-2,\\\:\mathrm{Second\: problem:\: }-3[/tex]
Step-by-step explanation:
The slope of a line passing through points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is:
[tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plugging in any two points in the table we have:
First problem:
[tex]m=\frac{1-5}{2-0}=\frac{-4}{2}=\fbox{$-2$}[/tex]
Second problem:
[tex]m=\frac{-1-5}{2-0}=\frac{-6}{2}=\fbox{$-3$}[/tex]
