What is the simplified expression for 6(2(y+x))

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?
