Question

A group of friends are hiking on trail Y when they reach an intersection with trail X. Trail X is perpendicular to trail Y. If trail Y has a slope of - which of the following statements are true?

A.Trail X is steeper than trail Y. 
B.Trail X has a positive slope (it runs uphill). 
C.Trail X has a negative slope (it runs downhill). 
D.Trail Y is steeper than trail X.

Answer 1

So because trail Y has a negative slope, and X is perpendicular to Y the X has a positive slope. \ <---- neg slope y and / <----- pos slope x
