Updating Graphs To Be Easier To Read

Please, please, please make the graphs easier to read. I constantly get questions wrong because I can not accurately read the graphs. The very light gray grid lines are too tiny, too thin, and too close together to distinctly tell them apart. I understand that you want to test our ability to read graphs, but when I was supposed to do the equation with a (3.75, 2) point and I get it wrong because I read the graph as (3.5, 2) it is very frustrating! It makes me feel like I am taking an eye exam instead of a math exam. 

To be clear, I wear glasses and I have had a recent eye appointment, so I don't believe this is an issue with my eyes but rather an issue with accessibility.  

If there is already a solution for this, like a way to zoom in on the graphs or change the settings please let me know! If not, please consider adding such features, thank you!
