X and Y Spacing are the "Grid marks" when you want them shown.  The larger the number, the fewer and further between Grid marks.

Say UNIT = INCH

At 10=X and 10=Y, grid marks will occur every 10" x 10" and the distance between each adjacent pair will be 10".

At 1=X, 10=Y there will be 1" x 10 marks in the X direction and 10" x 1 mark in the Y even though, zoomed out, there are lines of intersection only every 10".  Zoom in to see the smaller "X" marks.

A simple LINE from 0,0 to @10<45, then ALIGNED Dimension from ENDPOINTS makes the point clear in the 1=X and 10=Y.
