24. The following data resulted from a stress-strain experiment where a given strain was applied and stress measured. Negative values of stress indicate compression Deformation D Stress S (MPa) -2 -8.5 1 -1.2 0 0.2 3 10.5 We want to apply linear regression to find the value of a and b in the equation S =D +00 The problem will involve the assembly of an overdetremined linear syster of the type Ab where x is the unknown vector with the values of a and b. Which of the following is the correct A matrix?
