Given expression: 
In order to simplify it to get an equivalent expression, we need to multiply all terms.
Let us simplify 
Therefore, 

=
.
<h3>Therefore,

is equivalent to

</h3>
When you set up 3 * (1/3), you're both multiplying and dividing by a 3. these two cancel out, and you're left with one. 3 *(1/3) is simply 1.
12 * (1/3), when you set it up, doesn't cancel out the same. multiply straight across the top (12 * 1), then divide by the bottom (3). 12/3 = 4, so 12*(1/3) is 4.
9 * (1/9) gives you the same result as the first one. the multiplied 9 and the divided 9 cancel out, and you're left with 1.
The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
