Question 1144721: For B, is there an equation that can help me find the distance between the two point or is it just subtract 1 point from the middle point?
Consider the points (-1, 7) and (4, -8).
a. Find the midpoint of the line segment with the given endpoints. Show work.
M = (Xa+Xb)/2, (Ya+Yb)/2
M = (-1+4)/2, (7+(-8))/2
M = 3/2, -1/2
M = 1.5, -0.5

b. Find the distance between the points. Give the exact answer (involving a radical), simplify the radical as much as possible, and also state an approximation to three decimal places.

--------------------------
Consider the points (-1,7) and (4,-8).
a. Find the midpoint of the line segment with the given endpoints. Show work.
------------
Find the average of x and of y separately.
For x: (-1 + 4)/2 = 3/2
For y: (-8 + 7)/2 = - 1/2
Midpoint is (3/2,-1/2)
