The x column increases by 1 and the Y column decreases by 1.

4 - 6
5 - 5

I'm sure you can take it from there.

as the x increases by 1, the y appears to decrease by 1

y = -x + 10

for x=4 , y = -4+10 = 6 , yup, that fits the pattern
for x =8, y = -8+10 = 2

etc.

(notice x=12, y=-2 fits my pattern)
