Y=3X+4 THE Y INTERCEPT(b)=(0,4)
\n" ); document.write( "NOW SET Y=0 & SOLVE FOR X
\n" ); document.write( "0=3X+4
\n" ); document.write( "3X=-4
\n" ); document.write( "X=-4/3 THUS THIS POINT IS (-4/3,0)
\n" ); document.write( "NOW PLOT THESE 2 POINTS & DRAW THE LINE THROUGH THEM WITH A SLOPE (m) OF 3.
\n" ); document.write( "[THIS IS THE RED LINE].
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "Y=-3X-4 HAS A Y INTERCEPT OF (0,-4)
\n" ); document.write( "NOW SET Y=0 & SOLVE FOR X
\n" ); document.write( "0=-3X-4
\n" ); document.write( "-3X=4
\n" ); document.write( "X=4/-3 THUS THIS POINT IS (-4/3,0)
\n" ); document.write( "NOW PLOT THESE 2 POINTS AND DRAW A LINE THROUGH THEM WITH A SLOPE (m) OF -4/3
\n" ); document.write( "[THIS IS THE GREEN LINE]
