Question

How do you name the Constant of Variation in the equation, `y=x`?

Answer 1

Constant of variation: `1`

Explanation:

If `y=c*x` for some constant `c`
then there is a direct variation between `x` and `y` with a constant of variation`=c`

Since `y=xcolor(white)("XX")hArrcolor(white)("XX")y=1*x`
`x` and `y` are in direct variation with a constant of variation `=1`
