(4,5)
Step-by-step explanation:
Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.
Ex: (x,y) would become (-y,x)
Quotient means division, which is obvious by all the division answers.
It says "Quotient of 4 AND ..." which means that four will be on top and everything else will be on the bottom.
So now you have:

four over something unknown.
Reading the rest of the question, "the sum of a number and three"
Sum means addition, again obvious by the answer choices.
"a number" is an unknown, so we can set that to x
and this x is being added to by three, so therefore
x+3 would be in your denominator.
You final equation should look like this:;

OR answer choice
A
Answer:
