\n" ); document.write( "\n" ); document.write( "Which equation represents a line which is parallel to the line \"y=-2x-4\"?\r
\n" ); document.write( "\n" ); document.write( "this line \"y=-2x-4\" has a slope \"-2\"\r
\n" ); document.write( "\n" ); document.write( "recall: parallel lines have \"same+\"slope, so write all equations in slope intercept form\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a.
\n" ); document.write( "\"y%E2%88%922x=3\"=>\"y=2x%2B3\"=>slope is \"2\"=> it's not parallel line to given line\r
\n" ); document.write( "\n" ); document.write( "b.
\n" ); document.write( "\"x%E2%88%922y=%E2%88%924\"=>\"x%2B4=2y\"=>\"y=x%2F2%2B2\"=>slope is \"1%2F2\"=> it's not parallel line to given line\r
\n" ); document.write( "\n" ); document.write( "c.
\n" ); document.write( "\"x%2B2y=16\"=>\"2y=-x%2B16\"=>\"y=-x%2F2%2B8\"=>slope is \"-1%2F2\"=> it's not parallel line to given line\r

\n" ); document.write( "\n" ); document.write( "\"2x%2By=7\"=>\"y=-2x%2B7\"=>slope is \"-2\"=> it \"IS\" parallel line to given line\r
