    First, like any equation, we would subtract 9 from both sides, right?

    We take the constant off. So subtract 9 from both sides. There is your answer

    -2 (greater than/equal to sign) -p would be the answer?

    No, - and - equals positive. your answer will be in positive

    so we subtract and get -2 so now we have'' −2≥−p now Multiply both sides by −1 what do we get?

    2 is greater than or equal to p

    I agree,the answer is 2 is greater than or equal to p, but IXL says that p is greater than or equal to 2. WHy are they doing this? IXL is adding p to both sides.

    \[-2 \ge-p\] multiply by -1 \[2\le p\] or \[p \ge 2\]
