what is $(h,k)$ supposed to be in coordinate geometry

Question

I was doing some math questions and had difficulty answering any question that had $(h,k)$ in it I would highly appreciate it if you could help me.

Answer 1

h and k are simply variables used to refer to a point in two dimensional geometry function.. They have the same function as x and y in algebra.

A relation between h and k helps us to find the locus of a moving point. If one of the coordinates depends on the other, then the point for different values of the variable ( the variable servers as a parameter) will trace out a definite path which is called the locus.

Answer 2

$(h,k)$ is a point whose horizontal coordinate is a number represented by the variable $h$ and whise vertical coordinate is represented by $k $. $(h,k) $ is usually used for a special point (like the center or vertex of graph) when the variable names $x $ and $y $ are being used for something else, like the coordinates of an arbitrary point on the graph.
