Function 1 is non-linear as the value of y is fixed irrespective of x value

Here, we want to check if the given set of points represent a linear or non-linear equation

If the function is a linear equation, then there exists a fixed relationship between the x-values and y-values for all set of points.

Now, looking at the first function, the value of y is the same irrespective of the x-value

This shows that it is not a linear equation as the y-value is expected to change with changing x-values where the relationship between x and y at any point in time is the same.
