Best ResponseYou've already chosen the best response.1ok replace your x and y with 4 and 1 respectively to find the C so that your graph for your equation will go through that point

Best ResponseYou've already chosen the best response.0so y=sqrt((x^2/16) + c) and i plugged in (4,1) and got y=sqrt((x^2/16) is that correct?

Best ResponseYou've already chosen the best response.1You have \[C=8y^2\frac{x^2}{2}\] Replace x with 4 and y with 1 like this: \[C=8(1)^2\frac{(4)^2}{2}\] Is this what you did to solve for C?

Best ResponseYou've already chosen the best response.1I can't do arithmetic somethings lol But you have \[0=8y^2\frac{x^2}{2} \]

Best ResponseYou've already chosen the best response.0hmm it the system doesn't seem to accept it.. it says it isn't a linear equation

Best ResponseYou've already chosen the best response.1Ok solve for y make sure you keep in mind we want to go through the point (4,1)

Best ResponseYou've already chosen the best response.0oh wait y=x/4 works!!

Best ResponseYou've already chosen the best response.1We wanted y=x/4 That is why I said to keep in mine we want it going through (4,1) :)

Best ResponseYou've already chosen the best response.1The equation y=x/4 doesn't satisfy the point (4,1) but y=x/4 does
