Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then select none. When m<7=m<8 AD || BC
AB || DC
none

AB || DC

Step-by-step explanation:

cause  Well,  since AB and DC arent touching anothers line, then that will be paralell because paralell is two or more lines that arent ever going to touch another line

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)
