The given expression is 
We see from the possible answers they are all in reduced form - variables are grouped together. That means we should also reduce the given expression to see which answer is equivalent to it.
Let's expand the term inside the parentheses first, by multiplying each term inside by the coefficient of the parentheses, -3.
Now let's group terms which have the same variables.
We can see that there are two groups:
Let's evaluate them separately. We just need to reduce each group now, since we've already grouped similar terms.
If we put the groups back together into the expression,
We can see that
. So (D) is the answer. Hope this helped.

Answer: No, he should have put the x values in the denominator and the y values in the numerator
Step-by-step explanation:
The formula for calculate the slope is:
You can observe in the formula that the y values must be in the numerator and the x values must be in the denominator.
Then, the correct slope is:
Then, Garret's slope is incorrect, because he should have put the x values in the denominator and the y values in the numerator.
