Corrections for #5

5.) A coordinate grid has the following set of ordered pairs:
(-2,-5), (0,-4), (3,0), (4,1), (5,2), (6,3).
The point (0,-4) is out of place. TRUE or FALSE?
How to find the solution:
  1. First, lets find the points of these coordinates.
  • You can see that the coordinates (-2,-5), (3,0), (4,1), (5,2) and (6,3) will form a straight diagonal line.


And (0,-4) is out of place 1 unit vertically down. So your answer should be TRUE.

Here's a video talking more about the Cartesian plane. I hope this helps.
