If a coordinate system is superimposed on the softball diamond in the figure below with the positive x-axis along the line from home plate to first base and the positive y-axis on the line from home plate to third base, what would be the coordinates of home plate, first base, second base, and third base?
home plate (x, y) = first base (x, y) = second base (x, y) = third base (x, y) =
Draw the coordinate axes on the diamond. The coordinates of home plate are pretty easy to find.

You need to read carefully and follow directions to place the coordinate system the way the want you to.
It's a 30, 60, 90. Could I use those ratios to help me?

No. It's not 30-60-90. You did not place the coordinate system correctly. Let's do it together. Look at the figure I drew above.
Okay, what did I do wrong?
What does this statement mean? "the positive x-axis along the line from home plate to first base "
It's referring to the triangle that it would form from home plate to first base
I don't see any triangle mentioned at all. It is telling you how to place the positive x-axis on the diamond. Can you show me on my drawing where "the line from home plate to first base" is?

Oh, I see now.

How would we find the coordinates using that?
Your drawing is still incorrect because you are not following the instructions. Yes, you circled home and first which means you see them. Now you need to place the positive x-axis, a ray, over the line that connects home base to first base.
Now that I know you know where home plate and first base are, can you show me the line that connects them?
