If we plot the points we get

Now draw a curve through these points to get the equation:

Now if we find the equation of the line through those points, we get the equation

note: let me know if you need help with finding the equation of the line.

Is the degree of the polynomial odd or even?
The degree is odd since one end of the polynomial goes in the positive y direction and the other end goes in the negative y direction.

Is the leading coefficient of the polynomial positive or negative?
Since the leading coefficient is -2, this means that the leading coefficient is negative.

Number of zeros?
From the graph, we can see that there is only one zero
