Linear or Not?

Determine whether the following function is linear    y = x^3 - 3x   Explain why      



y =3/2x - 3 Provide this equation with the standard form of itself and what 2 points they intercept. As well at a Table Of Values starting at -4 for x!  


Find equation whose x intercept iof a line is 4 and y intercept is 8.

In my book, it says the answer is (x)/4 + (y)/8 = 1   I have no idea how to solve to get to that answer.
