Question

Plot the segment PQ with endpoints P(-1,-4) and Q(3, 1) on the coordinate plane. Then find the length

and midpoint of PQ. Enter the midpoint coordinates as a decimal if necessary

Answer 1

Length of midpoint of porque=sqrt41=6.4

Explanation:

d= sqrt [(-1-3)^2 + (-4-1)^2)]

= sqrt [ (-4)^2 + (-5)^2]

= sqrt(16+25)

= sqrt 41 = 6.4

Midpoint coordinates: (1, 3/2)

(-1+3)/2 = 1

(-4+1)/2 = 1.5
