Answer :
The given data is incorrect, k does not constitute a constant, but rather y does not varies directly to x.
What is defined as the direct variation?
- A simple connection between two variables is described by direct variation.
- If y=kx, we say it varies significantly with x (or even as x in some textbooks) for some constant k, known as the constant of variation or the constant of proportionality.
- Because y varies directly with x, it would fit a equation y=kx for each and every point with in set.
We may have 11=7k for the initial point, implying that k=11/7.
Again for second point, we'd have 13=8k, which means k=13/8.
Using proportions, we can see that 11/7 doesn't really equal 13/8: cross multiply and you get 11*8=7*13, or 88=91.
Thus, this is incorrect, k does not constitute a constant, but rather y does not varies directly to x.
