Answer:
The slope between the two given points is -8.
Explanation:
1. Know the formula for finding the slope between two points.
![Slope(m)=(y2-y1)/(x2-x1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/s1uymb0tohhw23i3csjcz6uk8d0o6q2bwk.png)
2. Use (8,1) as your (x1,y1) and use (7,9) as your (x2,y2).
![m=(9-1)/(7-8)](https://img.qammunity.org/2021/formulas/mathematics/college/o1w1e45mz2rmff6mrwbgsq9an5iow31f52.png)
3. Simplify the equation so you can find your slope.
![m=(8)/(-1) = -8](https://img.qammunity.org/2021/formulas/mathematics/college/lfp7mpb5bekj6muzftxs6q9ug2nrtmgmzp.png)
So, the slope between (8,1) and (7,9) is -8
