did you find the equation for the slope of the curve?

wait.. i'll solve for the slope

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

the value of b is the answer then?

thanks! what i got was 31/5 .. is this correct?
 one year ago

eroshea Group TitleBest ResponseYou've already chosen the best response.1
i follow the steps satelite gave

I think you wandered off the path...

phi Group TitleBest ResponseYou've already chosen the best response.0
see the plot I posted up above
 one year ago

eroshea Group TitleBest ResponseYou've already chosen the best response.1
where is the normal line there?
 one year ago

eroshea Group TitleBest 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
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
what did you get for the slope ?
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
first, what did you get for the derivative?
 one year ago

eroshea Group TitleBest ResponseYou've already chosen the best response.1
owh wait.. i got a mistake
 one year ago

eroshea Group TitleBest ResponseYou've already chosen the best response.1
b = 46/5 .. i believe that is the correct answer now?
 one year ago

phi Group TitleBest ResponseYou've already chosen the best response.0
yes, 9.2 which matches the plot
 one year ago

eroshea Group TitleBest ResponseYou've already chosen the best response.1
9.3 :)) thanks so much! help me again.. i'll post a question :)
 one year ago

eroshea Group TitleBest 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?

eroshea Group TitleBest ResponseYou've already chosen the best response.1
lol.. i got a mistake again. sorry.. yes.. 9.2
