Find the distance between A and B.

A= the coordinates ( 6, 1)

B= the coordinates ( 2, -3)

answer choices are:
A. 8 units
B. 16 units
C. 2 times the square root of 2 units
D. 4 times the square root of 2 units

    the distance is the length of the hypotenuse of the right triangle whose legs are 4 and 4

    Looks like (D)

  • math(algebra) - ,

    -3 - 1 = -4
    2 - 6 = -4
    sqrt [(-4)^2 + (-4)^2] = sqrt (2*16)
    = 4 sqrt 2
