Question 1056967
.
The question states: 
The vertices of triangle ABC are A(-5,3), B(2,2) and C(-1,-5). Which of the following is the length of the matrix from vertex B to side AC? 

I am told to find the mid point by computing as follows: (((-5 + -1)/2), (3+-5)/2). 
Why do I add -5 to -1 to get -6 instead of finding the distance between them to get -4?
