You can put this solution on YOUR website!
Assuming x is the independent variable:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Isolate y to get y = 10-3x, so y is a function in x. Or you could replace y with y(x) (or whatever symbol you prefer) for function notation, i.e. y(x) = 10-3x.
\n" ); document.write( "
\n" );
