Explain how multiplying with 6 is like multiplying 3.

it is multiplying 3 but doubled

Step-by-step explanation:

because 6 is exactly double the number of 3, meaning that half of the solutions found on a multiplication table of 3 can be found with six, and all of the soluations on a multiplication table of 6 can be found on 3.  

Step-by-step explanation:

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)
