The point P(1,6) is closest to the origin along the x-axis.
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Here we have four points that are:-
P(1, 6), Q(5, 3), R(6, 1), S(3, 6)
As we can see that point P has the minimum value of x which is 1. I have also plotted the point on the graph attached with the answer.
Hence the point P(1,6) is closest to the origin along the x-axis.
