Answer:
B. The line is shifted down 8 units
Explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
==============================================
We have y = 3/7x + 6. It has been changed to y = 3/7x - 2.
y = 3/7x + 6 → f(x) = 3/7x + 6
f(x) - 8 = (3/7x + 6) - 8 = 3/7x + 6 - 8 = 3/7x - 2
