Hi everyone!

I need help extending my OLS line of best fit - not sure how to do it? Please see below for details : )

Here is my plot:

Now, with this scenario my R2(squared) is very high and I find this line of best fit valid per say, therefore, when scrolling further on my x/y-axes ranges I would like to make this line **extend** let’s say for up to ‘Jan 2020’ x-tick; how would I do that? Also, because my x-axis is ‘Date’ - my slope turns out to be gibberish and I cannot use the equation to calculate further values into the future (snippet of slope below):

Please let me know how to approach this problem, all help is appreciated!
