Y=-2X-4 THIS LINE HAS A SLOPE OF (-2). (RED LINE)
\n" ); document.write( "A PERPENDICULAR LINE TO THIS LINE HAS A SLOPE OF (1/2 OR .5) THE NEGATIVE RECIPROCAL OF THE OTHER LINE.
\n" ); document.write( "NOW REPLACE THEX & Y TERMS IN THE LINE EQUATION[Y=mN+b BY ONE SET OF (X,Y) POINTS & THE SLOPE VALUE OF .5 7 SOLVE FOR THE Y INTERCEPT (b). THUS:
\n" ); document.write( ".5=.5*-.5+b
\n" ); document.write( ".5=-.25+b
\n" ); document.write( "b=.5+.25
\n" ); document.write( "b=.75 SO THE EQUATION FOR THIS LINE IS :
