Pick all that are equivalent to 3(-4) and/or result in the same solution. A-3(-4)
12
C-12
D -26)
E -3(4)

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)

i think the correct option is the second option.

or

it’s the first one your welcome
