Answer:
Option B is correct.
direct variation; k = 5/2
Step-by-step explanation:
The Direct variation says:
then the equation is of the form: ......[1] where k is the constant of variation.
From the given table:
Consider x = -2 and y = -5
Substitute these in [1] to solve for k;
or
5 = 2k
Divide both sides by 2 we get;
⇒ the equation becomes:
Check:
Take x = 4 and y = 10;
10 = 10 True
Therefore, the direct variation ; best describe the function represented by the table
