Is y=4/6-2x a linear expression

Step-by-step explanation:

No it is an equation (equal sign)

specifically y = mx + b form

Yes, but y = - 2x+4/6 is the correct order of the function

Step-by-step explanation:

It is, but it is not in descending order.

To fix this we need to put - 2x as the first term

since it is negative it would be written as y = - 2x

4/6 is positive and a constant, so to add it to the equation we put it behind the variable term

y = - 2x+4/6
