Use the point-slope formula

\n" ); document.write( " $\"+%28+y+%2B+3+%29+%2F+%28+x+%2B+2+%29+=+%28+-9+%2B+3+%29+%2F+%28+-7+%2B+2+%29+\"$
\n" ); document.write( " $\"+%28+y+%2B+3+%29+%2F+%28+x+%2B+2+%29+=+%28-6%29+%2F+%28-5%29+\"$
\n" ); document.write( " $\"+%28+y+%2B+3+%29+%2F+%28+x+%2B+2+%29+=+6%2F5+\"$
\n" ); document.write( "Multiply both sides by $\"+5%2A%28+x+%2B+2+%29+\"$
\n" ); document.write( " $\"+5%2A%28+y+%2B+3+%29+=+6%2A%28+x+%2B+2+%29+\"$
\n" ); document.write( " $\"+5y+%2B+15+=+6x+%2B+12+\"$
\n" ); document.write( " $\"+5y+=+6x+-+3+\"$
\n" ); document.write( " $\"+y+=+%286%2F5%29%2Ax+-+3%2F5+\"$
\n" ); document.write( "------------------
\n" ); document.write( "Does the line go through (-2,-3) and (-7,-9) ?
\n" ); document.write( " $\"+y+=+%286%2F5%29%2Ax+-+3%2F5+\"$
\n" ); document.write( " $\"+-3+=+%286%2F5%29%2A%28-2%29+-+3%2F5+\"$
