Declared that entered the union with equal status as exiting states - land ordinance of 1765 or - northwest ordinance of 1787

Northwest Ordinance of 1787.

Explanation:

The Northwest Ordinance was an act passed on July 13, 1787.  This law created the Northwest Territory, in the current Midwest region. In addition, this law established the principle by which all the territories annexed to the United States would be incorporated as new territories that, if they met the required population parameters, could apply to be new states of the nation, instead of joining any of the 13 original states of the country. In this way, this law guaranteed that new states were incorporated into the Union as the country began to expand.

the section of the chart that represents a point at which a bill needs approval from a majority of people in both chambers to advance is j, as this is the only section before the bill becomes law which has both rows (symbolizing the chambers) converging into one, meaning that the two parts of the congress have to approve of it before it can march on with the process.
