Step-by-step explanation:

I don't think you should be asking for answer on a quick assessment.  This is something you're supposed to have down cold.  I'm not judging, just saying,  you should know this.  :/   why don't you?  :/  I'm reporting you to mathpol poplice  :P  ( don't worry there is no such thing )

1)

4 - 2

put into improper fractions

-

move to same denominators

-

subtract numerators

reduce

3)

4)

5)

do all of 2-5 with the same strategy as I did in 1).  Practice this yourself , so  you do get it.

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)
