Hello, thank you for taking the time to post your question!
To rewrite this expression in standard form, you want to isolate the squared term of y^2.
In this case that means multiplying both sides of the equation by 8 in order to simplify
x = 1/8y^2
8x = y^2
Meaning that the standard form for the given equation is y^2 = 8x
I hope that helps you get moving in a better direction on this type of question! Feel free to reach out if you have any additional questions beyond that :)
