Any help?

None of your y values appear to fit the given equation!

Solve the equation for y: $$xy=-4$$$$y=-\dfrac{4}{x}$$Now plug all of your values of x into that formula and write down the resulting y-values.  For example, x = -3, y = -4/-3 = 4/3.

@whpalmer4 I'm not really sure how to solve my y values..  I tried for a long time, and even checked some algebra books, but I couldn't figure it out.

It's just arithmetic.  For x = -2, y = -4 / -2 = 2.  For x = -1, y = -4 / -1 = 4.  And so on...it's too simple :-)
