9 is an odd number it cannot be divided by 4. The correct option is C.
What is coordinate geometry?
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
On a coordinate plane, the given points (2, 1), (6, 3), (9, 4) and (12, 6). In the given points there is a constant ratio between them.
The constant ratio will be determined as:-
(2, 1) ⇒ 2 : 1
(6, 3)⇒ 6 : 3 ⇒ 2: 1
(9, 4)⇒ Can not be divided.
(12,6)⇒ 12 : 6 ⇒ 2 : 1
As it is observed that 9 can not be divided by 4 to give the ratio of 2: 1. Hence, 9 has an odd ratio out of other ratios.
Therefore, 9 is an odd number it cannot be divided by 4. The correct option is C.
