Question

Find the distance between P and Q and the coordinates of the midpoint of the segment joining P and Q if P(2,7), Q(4,1).

Answer 1

distance= 6.3245 and midpoints: x=3 & y=4

Explanation:

using distance formula:

S=√(x₂-x₁)² + (y₂-y₁)²

S=√(4-2)² + (1-7)²

S=√(2)² + (-6)²

S=√4+36

S=√40

S=6.3245

For midpoints,

x=x₁+x₂/2

x= 2+4/2 = 6/2 = 3

y=y₁+y₂/2

y= 7+1/2 = 8/2 = 4
