Answer:
5
Step-by-step explanation:
Based on the given points, the point that is located on the y-axis is (0,7).
<h3>Which point is on the y axis?</h3>
The point that is on the y-axis should have a coordinate such that x is equal to 0.
This leads to the point being on the y-axis because the nonzero coordinate of the y axis would then have to be placed on the same axis.
The only point with a 0 coordinate is (0, 7) so this is the point that is located on the y-axis.
