Solution:
Points are located on a cartesian plane using coordinates.
The coordinates are the x-coordinate and the y-coordinate
A cartesian plane is shown below with the quadrants.
A cartesian plane has four quadrants (I, II, III, and IV).
For points whose second coordinate is negative, this implies points whose y-coordinate are negative.
When a point has a y-coordinate as negative, it will lie on the negative y-axis plane.
To have a second coordinate as negative, the two possibilities are given below;
[tex]\begin{gathered} (+x,-y) \\ or \\ (-x,-y) \\ \\ \text{This means the point having a negative y-coordinate.} \\ (+,-),(-,-) \end{gathered}[/tex]To plot points having these coordinates, the points will lie in the quadrants as shown below;
Therefore, all points whose second coordinate is negative will lie in the third or fourth quadrant.
Therefore, OPTION 3 is the correct answer.
