Graphic Details and pinpointing coordinates

For the last few days, we have been working on Graphic Details and how to pinpoint a coordinate on a y-axis and x-axis. Here is some of my work.

         

                       

 at the top, there are my Graphic Details we had to find out how many cubes we needed to make 5 crosses and the total was  21.

and this is my graph on this we had to pinpoint our answers on this graph by finding the coordinates by the question that was asked and this is what we have been working on.
