Problema Solution
Find the distance between the points (-12,-7) and (-5,-4). Also find the midpoint of the segment that joins the points.
What is the distance?
What is the midpoint?
Answer provided by our tutors
distance = sqrt( (-12+5)^2 + (-7+4)^2 ) = sqrt( 7^2 + 3^2 ) = sqrt( 49 + 9 ) = sqrt( 58)
midpoint:
x = (-12 + -5 )/2 = -17/2
y = (-7 + -4)/2 = -11/2
then midpoint is ( -17/2; -11/2)
