Sagot :

Step-by-step explanation:

  • Direct variations are ALWAYS linear and ALWAYS go through the origin.

Because y = kx is linear function and y = 0 when x = 0

  • Inverse variations are NEVER linear and NEVER go through the origin.

Because y = k/x is not a linear function and x is never zero as we can't divide by zero.

Direct variations are __always_ linear and ___always__ go through the origin.

Inverse variations are _never___ linear and __never__ go through the origin.

  • For inverse variation i.e y=k/x putting x=0 makes it undefined
