You can put this solution on YOUR website!
First, let us find out the slope for the perpendicular line.
\n" ); document.write( "This equation:
\n" ); document.write( "(5)(m2)=-1
\n" ); document.write( "m2=-1/5
\n" ); document.write( "The slope of the perpendicular line is -1/5
\n" ); document.write( "Now, we need the second piece for the puzzle.
\n" ); document.write( "Use the point-slope equation which is $\"y-y2=m%28x-x2%29\"$
\n" ); document.write( "Plug them in:
\n" ); document.write( " $\"y-7=%28-1%2F5%29%28x-%28-3%29%29\"$
\n" ); document.write( " $\"y-7=%28-1%2F5%29x-%283%2F5%29\"$
\n" ); document.write( " $\"y=%28-1%2F5%29x%2B%2832%2F5%29\"$
\n" ); document.write( "Simplify the last fraction, which becomes 6 and 2/5
\n" ); document.write( "Here you go! \n" ); document.write( "

\n" );
