WebBefore we can find the curve that is best fitting to a set of data, we need to understand how “best fitting” is defined. We start with the simplest nontrivial example. We consider a data set of 3 points, ( 1, 0), ( 3, 5), ( 6, 5) and a line that we will use to predict the y-value given the x-value, . predicted ( x) = x / 2 + 1. WebThe "steepness" of a line is determined by 2 things. First, it is the slope, you're correct. But it is also determined by the rate each of the axes is increasing by.
