This is one of the math problems I see and think "When in the world am I going to have to solve this in a real life situation. Anyways, still gotta learn it." thanks for making it clear

I'm in a boarding school program called Prep 9, and this literally SAVED ME on my test today. If I would've failed my test, I don't think I'd make it through the spring semester. Passing that test (midterm) was important to me, and I'm going to be a Hotchkiss Bearcat thx to you!

thanks for this my teacher didnt bother teaching us what to do when you didn't get a y intercept for a point.

A little bit of Linear Algebra can definitely come in handy, here. Once you get your system of equations, write it as an augmented matrix, and then either use Cramer's Rule or get this matrix in Reduced Row Echelon Form (RREF). Other than that, great work!

[mvaranawat]

Thank you so much for this video! I had a problem like this and had no idea as to how I should approach it. Simple and straightforward, please continue making such content! :D
