How are babys made?
IDK

Once a month, the female releases an ovum (one egg) or sometimes two (ova). If an ovum has been released, and the couple have sex, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it's like a race and there is only one winner.

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)
