Which coordinate has not been plotted on the coordinate grid?

When we plot coordinates, we get their position on the 𝑥-axis and then their position on the 𝑦-axis. First let’s consider zero, zero. It’s a zero along the 𝑥-axis, zero units left or right. It’s also located at zero on the 𝑦-axis, zero units up and down. Zero, zero is located on this grid. We’re looking for the coordinate that has not been plotted on this grid.

So we need to keep looking. Is there a blue dot at coordinate zero, four? It would be zero on the 𝑥-axis and four on the 𝑦-axis. The intersection is where that point is zero, four. Zero four is plotted on this grid. And point two, four would be two units along the 𝑥-axis and four units along the 𝑦-axis. The intersection of the 𝑥 equals two and 𝑦 equals four is here. That point is located on our grid.

Point d — four, zero — would be located along the 𝑥 equals four and along the 𝑦 equals zero. The point four, zero would be here where the yellow point is. And that point has not been plotted on this grid. We’ll double check our last point: four, four. It’s the point located four units along the 𝑥-axis and four units along the 𝑦-axis. It is one of the original four points. Out of these five points, only one of the points wasn’t originally plotted on the graph. And that’s the point four, zero.
