Question

For the point P(-20,7) and Q(-13,12), find the distance d(P,Q) and the

coordinates of the midpoint M of the segment PQ.

Answer 1

Distance

`d(P,Q)=√((-20-(-13))^2+(7-12)^2) \\ \\ =√(49+25) \\ \\ =\boxed{√(74)}`

Midpoint

`M=\left((-20-13)/(2), (7+12)/(2) \right)=\boxed{\left(-(33)/(2), (19)/(2) \right)}`
