\n" ); document.write( "Press Y= with the graphing calculator and enter x-4 into y1
\n" ); document.write( "and 3x into y2
\n" ); document.write( "Then press graph
\n" ); document.write( "Then 2nd calc intersect

\n" ); document.write( "Draw a x and a y axis
\n" ); document.write( "Draw a dot on (0,-4) which is on the y axis go up 1 and right one as far as possible. Then do the opposite on the - side. Go down one left 1.
\n" ); document.write( "Draw another dot on (0,0) go up 3 and right 1 as far as possible . Then do the opposite on the - side go down 3 and left one. The points should connect and that is the intersection. It should be (-2,-6) if it has been done properly. \n" ); document.write( "
