Answer:
He is below his goal
Explanation:
see the attached figure to better understand the problem
Let
x -----> the number of weeks
y ---->skiing distance in kilometers
Looking at the graph of Jake's goal
we have the ordered pair (6,5)
That means
The number of kilometers from Jake's goal for week 6 is 5 kilometers
and
In the actual Jake is skiing at 4.5 km at week 6
so

therefore
He is below his goal
