how would you write an equation for each line example: through (-2, 1) and parellel to Y = -3x+1?
\n" ); document.write( " if the second line is parallel to the first then write the same equation as the first replacing the constant term with say k which is to be found out
\n" ); document.write( " Y = -3X+k
\n" ); document.write( " if this is passing through -2,1 then this equation should be satisfied by -2,1
\n" ); document.write( " which helps us to find k
\n" ); document.write( " we get ...1 =-3*(-2)+k = 6+k
\n" ); document.write( " 6+k=1
\n" ); document.write( " k=1-6 = -5
\n" ); document.write( " hence equation of a parallel line through (-2, 1) is
\n" ); document.write( " Y = -3X - 5
\n" ); document.write( "
\n" ); document.write( "
\n" );
