Answer:
the slope is undefined
Step-by-step explanation:
x=-1
The distance between town X and Town Y is equal to the difference between the distance between Town X and Town Z and the distance from Town Y and Town Z. Mathematically
d (X-Y) = d (X-Z) - d(Y-Z)
Substituting,
d(X-Y) = 57 miles - 28 miles = 29 miles
Thus, the distance from Town X to Town Y is 29 miles.
Answer:k=1,k=-2,k=
Step-by-step explanation:
Given two vectors
Distance between them is given by
squaring both side
k=1
angle between u and v is 90 i.e. orthogonal
=0
2+k=0
k=-2
angle between u & v is 
=0
k=
