Answer:
Neither
Step-by-step explanation:
step 1
Verify if the lines are parallel
we know that
If two lines are parallel, then their slopes are the same
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Compare
2/7≠7/2
therefore
The lines are not parallel lines
step 2
Verify if the lines are perpendicular
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
In this problem the slope of f(x) =2/7 and the slope of g(x)=7/2
Multiply
2/7*7/2=1
1≠-1
therefore
The lines are not perpendicular
