4•1\2=1/16
I don’t know the equation but you can just change it around a little
Standard form is x + y = number.
y = -2/5 x
y + 2/5 x = 0
2/5 x + y = 0
In standard form, the coefficient of x or y cannot be a fraction.
Therefore we have to multiply the whole equation by 5.
2x + 5y = 0

The function is in fact a polynomial and the degree of the polynomial is 7.
