the ordered pair (1, -2) is plotted on the coordinate plane.
where can you find this point?
starting at the origin, it is one unit left and then two units up.
starting at the origin, it is one unit right and then two units down.
starting at the origin, it is one unit right and then two units up.
starting at the origin, it is one unit left and then two units down.

Explanation:

In a coordinate plane, an ordered pair \((x,y)\) means: for \(x\) - positive \(x\) values move right from the origin, negative \(x\) move left. For \(y\) - positive \(y\) move up, negative \(y\) move down. The ordered pair is \((1, - 2)\), so \(x = 1\) (move 1 unit right from origin) and \(y=-2\) (move 2 units down from the \(x\) - position). So the correct description is "Starting at the origin, it is one unit right and then two units down".

Answer:

B. Starting at the origin, it is one unit right and then two units down.
