three points, A, B, and C exists in space such that B is "between" A and C. It is known that AB=7, BC=4 and AC=9. Are points A, B, and C colinear? Give a written explanation, supported by mathematical evidence, for your answer.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
