Linear fonction's equation : y = ax
So only in y = 2x
2 is the constant of <span>proportionality</span>
The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
