take the derivative replace \(x\) by \(4\) that gives you the slope take the negative reciprocal, that give you the slope of the normal line use the point slope formula with the point \((4,6)\) to find the equation of the normal line \(y=mx+b\) then \(b\) is where it crosses the y axis

I think you wandered off the path...

see the plot I posted up above

where is the normal line there?

erosheaBest ResponseYou've already chosen the best response.1
so what do you think is wrong with my answer? is the steps given by satelite somehow have mistakes? i just followed it

what did you get for the slope ?
 10 months ago

phiBest ResponseYou've already chosen the best response.0
first, what did you get for the derivative?

erosheaBest ResponseYou've already chosen the best response.1
owh wait.. i got a mistake

b = 46/5 .. i believe that is the correct answer now?
 10 months ago

phiBest ResponseYou've already chosen the best response.0
yes, 9.2 which matches the plot
 10 months ago

erosheaBest ResponseYou've already chosen the best response.1
9.3 :)) thanks so much! help me again.. i'll post a question :)
 10 months ago

erosheaBest ResponseYou've already chosen the best response.1
yes.. divide 46 by 5 right ? then it will be 9... remainder is 15.. that will be 3.. so 9.3?

lol.. i got a mistake again. sorry.. yes.. 9.2
