Answer:
The ordered pairs that are on the y-axis are: (0,0) and (0,1).
Explanation:
First: Review some basic stuff:
To find out when a coordinate pair is on the y-axis, we need to look at the x position of the coordinate. The x-coordinate has to be 0. The x on a coordinate grid controls the how much to the left or right a point on the grid is. If the x-coordinate is 0, it is not to the left or right of the axis that meets it at the point 0, 0 (which is the y-axis). That is why the x-coordinate has to be 0 in order for a point on the grid to be smack down on the y-axis.
Second: Find out the coordinate pairs that have a x-coordinate of 0.
But that brings up a question: Which one is the x-coordinate? Is it the first or the second? Well, when we're dealing with coordinate pairs, the x-coordinate is always first, and the y-coordinate always second (x, y). So we should look for a zero for in the numbers before the comma. The first two have 0 before the comma, so they will be the ones we'll select.
So, the ordered pairs that are on the y-axis are: (0,0) and (0,1).
