Question

Which of the equations are not linear? Why?

Answer 1

Answer:

For an equation to be a polynomial, the power of the independent or "x" variable of each term must be a whole number. The terms can be made up of constants and variables. If the equation is not a polynomial, it is not a linear equation. In the example, y = 7/5 - (6/5)x has one "x" term and its power is 1.

Answer 2

Explanation :

A linear equations forms a straight line on the graph

The general form of linear equation  is ,

                                          y=mx + c

 where, x and y are variables m is the slope of the line and c is the constant value

Example :

 3x + 2 = 5

The equations which does not obey these properties is considered to be not a linear equation
