Lets use process of elimination
Step-by-step explanation:
1. The order of the coordinate grid is like the alphabet. a comes before b, x comes before y.
2. Step 1 This eliminates 3 and 4. So we are left with 2 and 1.
3. It is not 1 because there is no a and b coordinate. There is only a Y and x one.
4. 4 is on the x axis, 6 is on the y axis.
5. Thus, the answer is 2.
