A coordinate plane is simply a 2D surface formed by the intersection of two number lines
The points are given as:
[tex](2, \frac 12)[/tex] and [tex](-4\frac 12, -1)[/tex]
In the above points, [tex](2, \frac 12)[/tex] is located in the first quadrant, while [tex](-4\frac 12, -1)[/tex] is located in the third quadrant.
The above means that, the coordinate plane that contains both points must extend from the first quadrant to the third, or vice versa
See attachment for the coordinate plane, and the points
