[Grade 11 Math: Functions] How do I find the equation of this line? I know all the points, but the line doesn't pass through any.

That is a best fit line for all the points. If you want to know the equation of that line you will have to know 2 points on the line (or approximations of them). With these (x1,y1) and (x2,y2), you can find the slope (m) using m = (y2 - y1)/(x2 - x1), and you can find the equation of the line by plugging in m and (x1, y1) into the point slope form y - y1 = m(x - x1).
Hope this helps!
