The equation for a straight line (deterministic model) is y = Bo +Byx. If the line passes through the point (-6,1), then x = -6, y = 1 must satisfy the equation; that is, 1 = Bo +(-6). Similarly, if the line passes through the point (9,2), then x=9, y=2 must satisfy the equation; that is, 2 = Bo + B1(9). Use these two equations to solve for Bo and By; then find the equation of the line that passes...
