You are asking for what value of k will make the lines have equal slope and equal y-intercept.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Putting both into slope-intercept form:
\n" ); document.write( "\"system%28y=kx%2B1%2F3%2Cy=-2x%2B1%2F3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"k=-2\" will make both lines coincide, being equivalent lines.
