Which of the following equations is not a linear equation?
(LOOK AT PHOTO!!!)

Answer 1

I think that B is not a linear equation.

Explanation:

Linear eqautions can not contain exponents in them. B has x to the power of 3 and y to the power of 2, ruling it out to be a linear equation.
I hope this helps! :)

Answer 2

`\qquad\qquad\huge\underline{{\sf Answer}}`

Linear equation has a degree of 1, that means the maximum power of a variable in a linear equation/expression should be 1. if an equation doesn't satisfy this condition then it's not a linear equation.

So, by Observing the choices, we get to the conclusion that the one which isn't a linear equation is B

`\qquad \sf  \dashrightarrow \: {x}^(3) - 5 {y}^(2) = 4`

Here, the variables have greater powers tham one, and degree is 3. so it's the required Answer ~
