A line segment is a straight line with finite length, and thus, have to endpoints(points on either end). The correct options are 2, 3, and 5.
<h3>What are the coordinates of the midpoint of the line segment AB?</h3>A line segment is a straight line with finite length, and thus, have to endpoints(points on either end).
Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:
and
The midpoint of the points P(3, –1) and Q(–7, –6) is,
x = (-7+3)/2 = -4/2 = -2
y = (-6-1)/2 = -7/2 = -3.5
Now, if we look at the options, the third option will give as the value of the x-coordinate as,
[(1/2)(-7-3)] + 3
= [(1/2)(-10)] + 3
= -5 + 3
= -2
This is the actual coordinate of the midpoint, therefore, this option is correct.
Similarly, the option two expresses the y-coordinate of the midpoint,
(-1 - 6)/2 = -3.5
Also, option five correctly depicts the value of y-coordinate,
-(5/2)-1 = -2.5 - 1 = -3.5
Hence, the correct options are 2, 3, and 5.

Hey there! I'm happy to help!
The Fertile Crescent is basically where human civilization started. It stretches from Mesopotamia and across the Mediterranean coast to Egypt. Early civilizations depended on agriculture. To make agriculture, you need a river because it is a good water source to help grow your crops.
If you look at the map I have provided below, you will see that there are tons of rivers. This would make it very easy for settlers to grow crops. This means that sea tides and eroding mountains aren't the answer. I don't think the rivers were flooding and natural canals is an oxymoron because canals are artificial waterways, but this all should give you and idea.
Have a wonderful day! :D
