2r - 9 ≤ -6

To solve for r, we must move all variables to one side.

So, let's start out by adding 9 to both sides.

2r - 9 + 9 ≤ -6 + 9

Simplify.

2r ≤ 3

Divide both sides by 2.

2r ÷ r ≤ 3 ÷ 2

Simplify.

\text{r}\leq\dfrac{3}{2}

Simplify so that we don't have improper fractions.

\text{r}\leq1\dfrac{1}{2}

Therefore, r is lesser than or equal to 1 \dfrac{1}{2}.

Using the process of elimination, we can see that the only answer choice that has \text{r}\leq1\dfrac{1}{2} in it is the THIRD answer choice.
