Juan plotted several ratios that represent the cost of plums at the local grocery store. When he finished his graph, he felt that one of the points was plotted incorrectly.

On a coordinate plane, the points (2, 1), (6, 3), (9, 4) and (12, 6) are plotted.

Which ratio is not equivalent to the others?
2 to 1
6 to 3
9 to 4
12 to 6

Respuesta :

Answer: 9 to 4

9 is an Odd number so it cannot be divided by 2

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.
