You can put this solution on YOUR website!
You made use of the point-slope formula
\n" ); document.write( "What you needed is the GENERAL point-slope formula:
\n" ); document.write( "( -3, -5 )
\n" ); document.write( "( -1, -4 )
\n" ); document.write( " $\"+%28+y+-%28-5+%29%29+%2F+%28+x+-%28-3%29%29+=+%28+-4+-%28-5%29+%29+%2F+%28+-1+-%28-3%29+%29+\"$
\n" ); document.write( " $\"+%28+y+%2B+5%29+%2F+%28+x+%2B+3+%29+=+%28+-4+%2B+5+%29+%2F+%28+-1+%2B+3+%29+\"$
\n" ); document.write( " $\"++%28+y+%2B+5%29+%2F+%28+x+%2B+3+%29+=+1+%2F+2+\"$
\n" ); document.write( "Multiply both sides by $\"+2%2A%28+x%2B3+%29+\"$
\n" ); document.write( " $\"+2%2A%28+y+%2B+5+%29++=+x+%2B+3+\"$
