Question 915981
house a's coordinate is (-5,10) and house b's coordinate is (-3,6). the property line is located exactly halfway between the two houses. it is also perpendicular to the line segment joining the two houses. please help find the equation of the property line. 
---------------------
Mid-point:: x = (-5+-3)/2 = -4 ; y = (10+6)/2 = 8
---------------------
Slope of the connecting line:: (10-6)/(-5--3) = 4/-2 = -2
-----------------------
Slope of the perpendicular line thru (-4,8):: 1/2
-----------
Equation Form::
y = mx + b
8 = (1/2)(-4) + b
8 = -2 + b
b = 10
-------
Equation:
y = (1/2)x + 10
