Question

What do you mean by constant ​

Answer 1

Step-by-step explanation: A constant, sometimes also called a "mathematical constant," is any well-defined real number which is significantly interesting in some way. A function, equation, etc, is said to "be constant" (or be a constant function) if it always assumes the same value independent of how its parameters are varied.

K is a constant in maths and since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. As previously stated, k is constant for every point; i.e, the ratio between the y-coordinate of a point and the x-coordinate of a point is constant.
