Hi there!
Answer:
x=0
<u><em>How it works:</em></u>
In coordinate planes, x always goes first. Then the y comes next. If x is 0, and y is also zero, none of those would be in the y axis place...
If the x is in 0 and the y is 1,2,3,4,5.... then the y axis would be in the y axis and x would just stay the same...
If the x is 1, then the y would be 0 which means that there would be nothing in the y axis.
Therefore, the answer is x=0..
