Mass and Acceleration. Force = Mass x Acceleration
The two variables that affect friction are the surface roughness of the materials in contact and the force pressing the surfaces together. As the roughness increases or the force increases, friction typically increases as well.
The power vs force graph shows that as power increases, force also tends to increase. This indicates a positive relationship between the two variables, where higher levels of power are associated with higher levels of force.
The two variables that affect the force of gravity are the mass of the objects involved and the distance between them. The force of gravity increases with the mass of the objects and decreases with the distance between them.
To calculate pressure, you need the force applied on a surface and the area over which the force is distributed. Pressure is defined as force per unit area (P = F/A), so these two variables are essential for the calculation.
Acceleration depends on the mass of the object and the net force acting on it.
The answer will depend on what variables are graphed!
Usually time but it could depend on the specific graph.

Its arbitrary - that's how the word (work) is defined.
