Answer:

Step-by-step explanation:
The problem is: given the points (19,−2) and (−11,10) find the slope of the line that joins them.
The slope of a line is the change in the y-coordinate over the change of the x-coordinate:
- slope = rise / run = Δy / Δx
Thus:
![slope=[10-(-2)]/[-11-19]\\\\slope=12/(-30)\\\\slope=-12/30](https://img.qammunity.org/2021/formulas/mathematics/college/nq0yj0kxyh3fwekrhg54y4lqz517w9xce6.png)
Simplify, dividing both numerator and denominator by 6:
