  1. Please learn the difference between geography and geometry.

    If you post your GEOMETEY answers and someone will probably check them for you.

  4. A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.
    A. 1.5
    B. -1.5
    C. 2
    D. -3
    ==================================
    I see no attempt by you to do these.
    I will show how to do two. Then you try.
    first:
    halfway between -9 and +6
    is
    (-9 + 6 )/2 = -3/2 = -1.5
    so B.
    ========================================
    second
    2. Find the coordinates of the midpoint ~hx(line over hx) given that H(-1,3) and X(7,-1).
    A. (3,1)
    B. (0,4)
    C. (-3,1)
    D. (-4,0)
    =============================
    halfway between in x = (-1+7)/2 = 6/2 = 3
    halfway between in y = (3-1)/2 = 2/2 = 1
    so
    (3,1)
    which is A.
    ==================
    Your turn.
