The law connecting friction F and load L for an experiment is of the form F =aL+b, where a and b are constants. When F =5.6, L=8.0 and when F =4.4, L=2.0. Find the values of "a" and "b "and the value of F when L=6.5.

Answer 1

I would sub in the first values for F and L to get an equation with a and b
then sub in the second set to get another eqution in a and b

Now that you have two equations in a and b, solve for a and b.

Now you have the actual equation, sub in L = 6.5
