Please help me Find the equation of perpendicular bisector of line segment with endpoints (3,-5) and (6,4)
\n" ); document.write( "----------------------------
\n" ); document.write( "The mid-point if [(3+6)/2,(-5+4)/2] = (4.5,0.5)
\n" ); document.write( "--------------------
\n" ); document.write( "The slope of the line thru the given points is (4--5)/(6-3)= 3
\n" ); document.write( "-------------
\n" ); document.write( "The slope of every perpendicular line must be -1/3
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( "The form of the desired line is y = mx+b
\n" ); document.write( "From the mid-point you know y = 1/2 when x = 9/2,
\n" ); document.write( "And you know the slope is -1/3
\n" ); document.write( "So, 9/2 = (-1/3)*(1/2) + b
\n" ); document.write( "b = 4 2/3 or 14/3
\n" ); document.write( "-----------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "y = (-1/3)x + (14/3)
