There is a youtube video with complete explanation. https://www.youtube.com/watch?v=3VQnW6yq1zs
If i am not getting your question correctly, please do let me know…

In linear regression when the algorithm solves the problem for co-efficients its actually a matrix solution which the algorithm does, it takes all Y values in one vector matrix, all x1, x2 in one matrix and then the bias “e” in one matrix and solves it for coefficients. Its been explained in the video as well.

Hope it is helpful, and I understood your question correctly… if i dont, please clarify, I will see if i can help you
