Question
In the table above, the ratio of y to x for each ordered pair is constant. What is the value of k ?
- 28
- 36
- 80
- 160
The correct answer is: 160
HINT :- Find the ratio and using the ratio find K.
Ratio of y : x at x = 1 and y = 4 is 4 : 1
As the ratio is constant at x = 40 and y = k we take 
,
∴ k = 160
