What part are you having trouble with?

anonymous · Answer

all of it i dont understand it, its a summer assignment problem

myininaya · Answer

A.
I assume you know the slope formula you learned in algebra because you are talking about tangent lines which means most likely you are a calculus student. 
Just use the slope formula.
Change of y/Change of x

You know two points on that line. 
Use the slope formula learned in algebra. Then we can proceed to B.
