<PRE><B>Question 1144721</B>
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.
------------
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)
==============================
	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.
----
{{{d = sqrt(diffx^2 + diffy^2)}}}
{{{d = sqrt(5^2 + 15^2)}}}
{{{d = sqrt(240) =  4sqrt(15)}}}
==================================
PS  Don&#39;t put a space after the comma in the points.
