Nettet8. jul. 2024 · The formula for the best-fitting line (or regression line) is y = mx + b, where m is the slope of the line and b is the y-intercept. This equation itself is the same one … NettetFor linear equations, we have y = m (slope) x + b (y intercept) and for exponential equations we have y = a (initial value)*r(ratio or base)^x. So in each case, we need to find two things. In both cases, the y intercept and initial value are found where x = 0 (y intercept) and the table gives us these, so linear b = 5 and exponential a = 3.

The original formula was written with Greek letters. This tells us that it was the population formula. But don’t forget that statistics (and data science) is all about sample data.
