\n" ); document.write( "the line whose equation is \"y+=+3x+%2B+5\" has a slope \"m=3\"; we can see it because this equation is written in slope-intercept form \"y=mx%2Bb\" where \"m\" represents a slope\r
\n" ); document.write( "\n" ); document.write( " the lines that are parallel to the line whose equation is \"y+=+3x+%2B+5\" \"MUST\" have \"same\" slope; so, compare given equation to answer options\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"6x+%2B+2y+=+12\"...........write it first in slope-intercept form
\n" ); document.write( "\"2y+=-6x%2B+12\"
\n" ); document.write( "\"y+=-%286%2F2%29x%2B+12%2F2\"
\n" ); document.write( "\"y+=-3x%2B+6\"...............as you can see, slope is \"-3\" and \"-3%3C%3E3\"; so, this is \"NOT\" your answer\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"-3x+%2B+y+=+8\"...solve for \"y\", move \"-3x\" to the right
\n" ); document.write( "\"+y+=3x%2B+8\"... as you can see, slope is \"3\" and \"3=3\"; so, this \"IS\" your answer\r
\n" ); document.write( "\n" ); document.write( "\"3y+=+9x\"
\n" ); document.write( "\"y+=+9x%2F3\"
\n" ); document.write( "\"y+=+3x\"..............as you can see, slope is \"3\" and \"3=3\"; so, this \"IS\" also your answer\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"y+=+-x\"....as you can see, slope is \"-1\" and \"-1%3C%3E3\"; so, this is \"NOT\" your answer\r
\n" ); document.write( "\n" ); document.write( "so, the equations of the lines that are parallel to the line whose equation is \"y+=+3x+%2B+5\" are:\r
\n" ); document.write( "\n" ); document.write( "\"-3x+%2B+y+=+8\" and
