Reading value from x-axis from trend line

I have a graph where I have forecasted the trend line to zero on the y-axis.

I want to be able to read/determine somehow the specific value on the x-axis where it crosses it at zero on the y-axis.

Thanks for any help.

Can you calculate this from the trend line equation, or is it horribly complicated?

Here's an example. I just want to know what the value on the x-axis is where the trend line crosses it.

Dear god, TheNorm you're right. Thanks very much, I am shocked I didn't realise this sooner
