slope is 7-(-1)/6-(-6) or 8/12 or 2/3. The midpoint is the average of the x s and the average of the ys
\n" ); document.write( "That is (0,3)
\n" ); document.write( "the first two points have and equation of a line between them of
\n" ); document.write( "y-7 = (2/3)( x-6) or y-7=(2x/3)-4; y=(2x/3) +3\r
\n" ); document.write( "\n" ); document.write( "perpendicular line's slope is negative reciprocal or -3/2
\n" ); document.write( "point slope formula using midpoint, which is (0,3), the midpoint of the x s and y s\r
\n" ); document.write( "\n" ); document.write( "y-3= (-3x/2)
\n" ); document.write( "y=-(3/2)x +3\r
