You can put this solution on YOUR website!
perpendicular lines have slopes that are negative reciprocals
\n" ); document.write( "this means that the slope of the line you are trying to find is 9/2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, (y-(-1))/(-8-(-10))=9/2 ... (y+1)/2=9/2 ... y+1=9 ... y=8\r
