The third option is the best fit for the application of a linear model.
In the first option, there is likely to be a correlation but it cannot be a linear one as goals are missed even from inside the keeper's box.
In the second option, it is safe to assume that each person will at least 2 other so this will follow an exponential model.
In the third option, the stopping distance is given by the equation of motion:
s = ut + 1/2 x at²
And this shows that the distance varies linearly with speed.
Answer:
-2
Step-by-step explanation:

Therefore, the average rate of change over the interval [-4,-1] is -2.
Answer:
x = y/12
Step-by-step explanation:
Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:
-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.
