Answer:
7) [tex]\frac{1}{2}\\[/tex]
8) [tex]-\frac{5}{4}\\[/tex]
Step-by-step explanation:

In graph 7, we can see that the points, [tex](-1,-4)[/tex] and [tex](1, -3)[/tex] are on the line so these can be our points [tex]1[/tex] and [tex]2[/tex]. Now we can find the slope.
[tex]\frac{-3 -(-4)}{1-(-1)} \\ \frac{-3 +4}{1 +1} \\ \frac{1}{2}[/tex]
The slope of line in graph 7 is [tex]\frac{1}{2}\\[/tex].
In graph 8, we can see that the points, [tex](-4,4)[/tex] and [tex](0, -1)[/tex] are on the line so these can be our points [tex]1[/tex] and [tex]2[/tex]. Now we can find the slope.
[tex]\frac{-1 -4}{0-(-4)} \\ \frac{-1 -4}{0 +4} \\ \frac{-5}{4} \\ -\frac{5}{4}[/tex]
The slope of line in graph 8 is [tex]-\frac{5}{4}\\[/tex].
