Answer:
The value of k remains constant for table 2
Step-by-step explanation:
Given tables of X values and Y values
To find which tables show the property of direct proportional:
Since Y is direct proportion to X
We write,
y=kx [Equation]
where k is constant of proportion.
Therefore, If the value of k remains constant for any table then, that table shows a direct proportion between y and x values.
For first table :
Now,
when x=1, y=3
Putting into Equation
y=kx
3=k(1)
k=3
Similarly, other calculations are carried out and put it into the form of a table
Note: Figure show tables of given and their respective k values.
Thus, the value of k remains constant for table 2
