\n" ); document.write( "\n" ); document.write( "2x+9y=7
\n" ); document.write( "add-2x to both sides
\n" ); document.write( "2x-2x+9y=-2x-7
\n" ); document.write( "9y=-2x-7
\n" ); document.write( "divide by 9
\n" ); document.write( "y= -2/9x -7/9
\n" ); document.write( "..
\n" ); document.write( "slope = -2/9
\n" ); document.write( "..
\n" ); document.write( "the slope of a lin perpendicular to this line will be 9/2
\n" ); document.write( "..
\n" ); document.write( "y = mx +b
\n" ); document.write( "(0,2)
\n" ); document.write( "plug the value of x,y to get b
\n" ); document.write( "2= 0+b
\n" ); document.write( "b=2
\n" ); document.write( "y= 9/2 *x +2 is the line
