Answer:
2
Step-by-step explanation:
The slope is the ratio of the vertical difference between two points to the horizontal difference. This ratio is often referred to as "rise over run."
From the point (-2, -1) to the point (2, 7), the rise is 7-(-1) = 8, and the run is 2-(-2) = 4. The ratio of these numbers is ...
slope = rise/run = 8/4
slope = 2
