NettetThe best way to do this is step by step. Step 1: Find where the graph intercepts the axes. y-axis is at x=0, so y-intercept is at y=e^ {b}+c. x-axis is at y=0, so x-intercept is at e^ {ax+b}+c=0, which is an equation we know how to solve. Note that if c>0 the graph does not cross the x-axis. NettetNormal Equations. The "normal equations" for the line of regression of y on x are: S y = a S x + nb and. S xy = a S x 2 + b S x. The values of a and b are found by solving these equations simultaneously.
