Extracted text: We will solve a simple linear regression problem. Suppose we want to fit a straight line to the following points: (1,4), (4,9), (6,11) Using the notation from the lecture notes, enter the following numbers corresponding to these points: () у - А Number (ii) x . A Number (iii) N Number (iv) x- x Number (V) у -х Number Use these values to formulate a system of equations (as shown in the lecture notes) which must be solved to find a and b such that the straight line to fit the data is y = ax +b. You should give your answers either in exact form or accurate to two decimal places. (vi) What is a? Number (vii) What is b? Number
