i filled in both x and y. and got a number. i used that as my slope in the equation yy1=m(xx1)

you get dy/dx =  (3sqrt(3))^(1/3)

steel11Best ResponseYou've already chosen the best response.0
dy/dx = x^(1/3) / y^(1/3) i replaced x and y with given points in this, and got 1.732

dy/dx = (3sqrt(3))^(1/3) / 1
 one year ago

CoolsectorBest ResponseYou've already chosen the best response.0
dy/dx = (3sqrt(3))^(1/3) i get 0.577

ok. go on with that then. what is the final answer?

y =1 0.577(x+3sqrt(3)) y= 1 0.577x 3 y = 0.577x 2

CoolsectorBest ResponseYou've already chosen the best response.0
in fact dy/dx = 1/sqrt(3) so : y = x/sqrt(3) 2
