Simplify and write the equation with positive exponents
-2x-2(1) Anything to the 0 power equals 1
-2x-2 Identity property of multiplication
-2/x2 The negative power means to move the x2 to the denominator
A negative exponent means that you take the reciprocal of what is being raised to the power. Since x is the only thing being raised to a negative power, it's the only thing that moves:
-2x-2y0 = (-2y0)/x2
Now, we also need to do something with y0. I will leave that and simplification to the student.
