I was told I have to use substitution or elimination but I forgot how to. I assumed previously I needed to solve for Beta0 and Beta1 via least squared equations, but my professor corrected me otherwise.
How do I use substitution/elimination for these equations?
It's linear algebra. You take the two equations with correct answers and combine them to find the equation for the line. During this you solve the B's but the answer isn't those it is the formula for getting (x, y). With B solved.
I asked the teacher and he told me it's solving linear equation via substitution or elimination. I also reviewed the lecture recording and I can confirm its y= MX+B where I have to find y-intercept and slope. The values for X and Y are already given so why would I try to find what they are?
They are given for two points not for any point. Which was the question. So yes it will be a MX + B for a straight line. But you get there by solving the previous equation, no formula book needed. But you need the value for M and B. Which mean you solved them.
