Implicit differentiation
chain rule is important here
I'll show the steps partially




now evaluate for (-2,2)
x=-2 and y=2



that's it, simplest form
SLope = (2 + 2)/(2 + 2) = 4/4 = 1

Step-by-step explanation:
Answer:
is not possible
Step-by-step explanation:
<u><em>The question in English is</em></u>
we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?
we know that
The formula to calculate the slope between two points is equal to

step 1
Find the slope ab
we have
a = (12 ,21) and b =(17,23)
substitute


step 2
Find the slope ac
we have
a = (12 ,21) and c =(3,9)
substitute


simplify

step 3
Compare slopes ab and ac
The slopes are different
That means ----> is not possible that a single road allows to join these three points
