Answer: I would say move 2 unit down
Explanation:
If y = (-10/6)x + 10 is the line in pic
And if the y-int move to 8 and keep using the same slope:
y = (-10/6)x + 8
If we were to draw we can see that we start at unit 8 then move 10 unit and move to the right 6 unit we can see that the line move down 2 unit.
