Test Corrections # 5



Question:

A coordinate grid has

the following set of ordered pairs: (2,-2), (0,-4), (3.0), (4,1), (5,2), (6,3). The point (0,-4) is out of place.






How I got the answer wrong:

Instead of plotting down (-2,-5), I plotted down (-2,-4). So now the points: (-2,-4) and (0,-4) look out of place. But the question said only (0,-4) was out of place not (-2,-5). So I wrote FALSE instead of TRUE. That is how I got the answer wrong.

Blue: (0,-4) - The number that was out of place.

Green: (-2,-4) - The wrong ordered pair
