You can put this solution on YOUR website!
I needed to have (x)(-10)(1)+(y)(1)(1)+(1)(4)(-1)-(1)(-10)(1)-(-1)(1)(x)-(1)(4)
\n" ); document.write( "-10x+y+(-4)-(-10)-(-x)-4y=0
\n" ); document.write( "this becomes:
\n" ); document.write( "-10x+y-4+10+x-4y=0
\n" ); document.write( "-3y-9x+6=0
\n" ); document.write( "-3y=9x-6
\n" ); document.write( "y=9x/-3-6/-3
\n" ); document.write( "(y)=-3x+2
\n" ); document.write( "But I want to know if that effects my answer? Is Y=-3x-2 correct.
\n" ); document.write( "I assumed you would complete the solution after the correction was provided?????? \n" ); document.write( "
\n" );
