I don't know how to place that image in this reply. However, I will try to describe it.

If both the abscissa (horizontal or X axis) and the ordinate (vertical or Y axis) have the lowest values in lower left corner, the points (dots) for the values would tend to group themselves going from the lower left to the upper right. This indicates that, as the value for one variable increases, the value for the other variable increases. That is a positive correlation on a scatter diagram (plot or graph).

I hope this helps. Thanks for asking.

it doesn't really . if you know year 7 simple stuff it might help

Since my explanation didn't seem to help, I searched Google under the key words "scatter diagram" to get these possible sources:
