$\"2x+%2B+y+=+-4\"$
\n" ); document.write( " $\"y=-2x-4\"$
\n" ); document.write( "Perpendicular lines have slopes that are negative reciprocals of each other.
\n" ); document.write( " $\"m1%2Am2=-1\"$
\n" ); document.write( " $\"-2%2Am2=-1\"$
\n" ); document.write( " $\"m2=1%2F2\"$
\n" ); document.write( "Now that you have the slope of the new line and a point on it, use the point-slope form of a line,
\n" ); document.write( " $\"y-yp=m%28x-xp%29\"$
\n" ); document.write( " $\"y-0=%281%2F2%29%28x-1%29\"$
