For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 56 N acts on a certain object, the acceleration of the object is 7 m/s 2. If the force is changed to 80 N, what will be the acceleration of the object?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
