Key idea

(x, y) = across, then up/down. Signs give the quadrant: I (+,+), II (−,+), III (−,−), IV (+,−). Reflecting across the x-axis flips the y; reflecting across the y-axis flips the x.

Sample problems

In which quadrant is (4, 7)?
In which quadrant is (−6, 1)?
In which quadrant is (−2, −8)?
In which quadrant is (3, −5)?

Common mistakes to watch for

Said Quadrant IV — plotted (5, −3) by reading the numbers in the wrong order.
Said Quadrant II — reversed the coordinates.
Said Quadrant II after checking only the first sign. Both signs decide the quadrant.

The answer key explains each one, so you can tell what a wrong answer means.
