How do I find a value on a line?

I made a line graph of data to use as a calibration. I know the y value and I
want to find the X value. Is there a way that I find find this specifically
on the line without using a trendline formula or guessing by looking at the
gridlines?

The only way to find a specific value is to use the formula.

If you can accept piece-wise linear interpolation, see
