Find the distance between the given points (-3, -7) and (-4, 15).
Thanks so much.

    The distance formula is ..

    given two points (x1,y1) and (x2,y2)

    distance= sqrt ((x1-x2)^2 + (y1-y2)^2)

  • Math -

    Did I do this problem correctly?
    D=sqrt[(15+7)^2+(-4+3)^2]
    D=sqrt[484+1]
    D=sqrt 485
    D ~22.023.
    Is this answer correct?
