If line is parallel to the given line $\"y=+4x+%2B+1\"$ , then it has an equation $\"y=+4x+%2B+b\"$
\n" ); document.write( "(Parallel lines have equal slopes)
\n" ); document.write( "To find $\"b\"$ substitute into the equation $\"x=-3\"$ , $\"y=1\"$
\n" ); document.write( " $\"1=4%2A%28-3%29%2Bb\"$
\n" ); document.write( " $\"1=-12%2Bb\"$
\n" ); document.write( " $\"b=1%2B12\"$
\n" ); document.write( " $\"b=13\"$
\n" ); document.write( "Answer $\"y=4x%2B13\"$ \n" ); document.write( "

\n" );
