Answer:
-1/5
Explanation:
It is an established mathematical proof that the slope of line A perpendicular to another line B is the recoprovaknofokad
Hence the slope of B = the negative reciprocal of B
Given that ; lines s and t are perpendicular ;
Slope of S = 5 ;
The slope of T = - 1/5
Answer: Suburban areas, (DONT pick Central city)
Explanation: I figured it out I think, it’s suburban areas cuz people work in the central city, however, they settle in suburban areas since suburban areas have cheaper land, and more space. Does that make sense? Also, central cities in developed areas are congested with very expensive land, so it would make sense that people would settle in suburban areas for less congestion. I hope this helps

Answer:
The main reason why mountains are rarely populated is because of the harsh climate that are dominating in those areas. On the other side, another important reason is that mountainous areas are not fertile enough and people are not able to grow crops. Lack of resources therefore is obliging people to move from the mountains to lower terrains.
Explanation:
Because of the mentioned reasons most of the people since the beginning of civilization were inhabiting river valleys and the areas that have better climate.
For example, Chinese civilization developed in the valley of Yangtze and Huang He and not Himalayas.
