Best ResponseYou've already chosen the best response.1y = 5/4 y+5/4 = 4(x1/2) this is a line equation ... so if form does not matter this would suffice

Best ResponseYou've already chosen the best response.1since x = 1/2 and NOT 1/2 you have to reevaluate the y you found

Best ResponseYou've already chosen the best response.0@amistre64 sorry,it was 3Y and not 3X that is how I got 11/12...

Best ResponseYou've already chosen the best response.0it is x squared so 1/2 and 1/2 both are same that is why i didnt change the y component

Best ResponseYou've already chosen the best response.1ohh then your derivative might need some looking at: x^2+3y3=0 2x +3y' = 0 y' = 2x/3 = 4 x = 12/2 = 6

Best ResponseYou've already chosen the best response.1(6)^2+3y3=0 33+3y=0, when y = 11

Best ResponseYou've already chosen the best response.1y+11 = 4(x+6) would be the tangent line
