What does the gradient of an acceleration VS force graph mean

i think its elastic potential energy (k) but i don't think so.
the question asks
Is the acceleration directly porpotional to the force? HOw do you know?explain
and the graph is a postive linear graph.

If F is directly porportional to a...then F=ka. What is k in the formula? (i think its the constant and the gradient)
How can we determine k form the graph? (slope formula i think which is rise/run).
Find it and compare it and comment.



Why do i have to go through this????WWHWYWHWYWHWYWY!gaidudsifjdsojsdgdsgpsigpsoi'msoangryidjdsig

[superflya]

the slope will be the amount that acceleration increases for a unit increase in force.

Acceleration is directly propotional to the Force if the mass is kept constant, since Newton's Second Law states that .
