Identify the missing equivalent ratios from the coordinate plane (7,2), (14,4), (21,6), (8,3), (16, 6)

For the given coordinate pairs, let's find the equivalent ratios by comparing their x-values and y-values:

First pair: (7,2)
The ratio between the x-values is 14:7, which simplifies to 2:1.
The ratio between the y-values is 4:2, which simplifies to 2:1.

Second pair: (14,4)
The ratio between the x-values is 21:14, which simplifies to 3:2.
The ratio between the y-values is 6:4, which simplifies to 3:2.

Third pair: (21,6)
The ratio between the x-values is 7:21, which simplifies to 1:3.
The ratio between the y-values is 2:6, which simplifies to 1:3.

Fourth pair: (8,3)
The ratio between the x-values is 16:8, which simplifies to 2:1.
The ratio between the y-values is 6:3, which simplifies to 2:1.

Fifth pair: (16,6)
The ratio between the x-values is 8:16, which simplifies to 1:2.
The ratio between the y-values is 3:6, which simplifies to 1:2.

So, the missing equivalent ratios are:
- (14,7) for (7,2)
- (16,8) for (8,3)
