I think the answer is the slope is -2 and the y-intercept is 12
P=3 and p=-1
First you subtract the number without a variable to the other side, so subtract one from seven, and subtract five from eight. After that just divide to make p by its self and you get the answer!!
1.No denominator contains a radical.
2.no radicand contains a fraction

Answer:
The demand will drop approximately 23 T-shirt per month.
Step-by-step explanation:
Consider the provided formula.

You currently sell T-shirts for $15 each and you raise your price by $2 per month,
That means p=$15 and 
We need to find how fast demand will drop.
So differentiate the above function with respect to time.


Substitute the respective values as shown:


Hence, the demand will drop approximately 23 T-shirt per month.
