Question
Several values of x and their corresponding values of y are shown in the table. A linear equation that represents the relationship shown in the table x=k , where k is a constant. What is the value of k?
The correct answer is: 2
For any value of y, the value of x does not change, such a function is called constant function.
x = k
here for any value of y, the x value is 2.
so, x = 2
k = 2
