Is the point (−3, 0) on the x-axis or y-axis? How do you know?

The point (−3, 0) is on the x axis.

I know because the point show us that

X=-3 and y=0

That means that the point that we will graph is on the -3 of the x axis. We don’t have to worry about the y because it’s equal to 0.

On the x-axis

since y=0
you know that the point didn’t go up or down, so it is on the x-axis
