mth.bz › fit › polyfitGiven Two Points Find A Linear Function. If points (-1, 1) and (0, 3) are given as points on a linear function: y = a x + b FUNction 1. then we can find a and b. Replace x and y with the coordinate values given to get the system: 3 = a (0) + b (1) 1 = a (-1) + b (1) Note that b = b (1) in both equations. The matrix equation for this system is:
