A specific net force is applied to an object, and it causes a certain acceleration. If the same net force is applied to a new object with four times the mass, what is the acceleration of the more massive object?

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?
