Question

find the distance between the pair of points with the given coordinates. (-16 15) and (-11 -3)

Answer 1

The distance between two points is given by the expression:
Be:
\[A(x,y,z)=A_x + A_y + A_z\]
and
\[B(x,y,z)=B_x+B_y+B_z\]
two points in R3
The distance is equal to the norm of the vector that is formed so:
\[D(AB)=\sqrt((B_x-A_x)^2+(B_y-A_y)^2+(B_z-A_z)^2) \]
For your points:
A(-16,15)-> \[A_x=-16\] \[A_y=15\] \[A_z=0\]
The same for B(-11,-3)
