Question

*FOR A GRADE* Which of the following gives an example of an equation that is NON-LINEAR?

A-y=x²-1
B-y=2x-1
C-y=x/4
D.y=2x

Answer 1

A

Explanation:

because this is the only equation based on an exponent greater than 1 of a variable.

x² makes it a non-linear equation.

all the other equations base on terms of x. x = x¹. and whenever an equation bases only on terms of x¹, the equation represents actually a straight line.

and for that reason these types of equations are called "linear".
