Hi, is it at all possible to determine the slope of a line after graphing it in Excel?

Is it possible to draw a second line tangent to another line?

And is it possible to draw best fit lines or curves? I've had to kind of fake it by drawing them myself, so I know they aren't very accurate, so it would be better if Excel can draw them itself.

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.

See the LINEST worksheet function.

Wouldn't that just be the original line?

See the Add Trendline feature of Excel charts.
