Thanks for the prompt reply to our question. When I shared the answer, I learned that my reference to this as a cartesian grid may have swayed the answer a bit. I should have noted it as a grid or graph – we’re not sure which because the x and y labels are throwing us off.

Please look closely at the sample and offer an opinion on whether it is, in fact, a grid or a graph, and offer an answer based on that. The sample attached to the original message is a bit fuzzy, but the main point to note is that each axis begins at 0 and ends with an arrow labeled with either x or y.

Thanks so much and know that we look forward to your response.
