(will give ! ) which shows solutions to x + 2y = 8 if x and y must be whole numbers.. . a.. {(8, 0), (6, 1), (4, 2)}. b.. {(2, 4), (1, 6), (0, 8)}. c.. {(0, 8), (1, 7), (2, 4)}. d.. {(0, 8), (1, 5), (2, 4)}

I don't think you can give medals on this site, but ok

a way to simplify it is to solve for y
x+2y=8
minus x both sides
2y=8-x
divide both sides by 2
y=4-x/2

(x,y)
just sub points in (sub x values for x and see if you get the coresponding y value)
example
point (8,0)
x=8 and the resulting y should eual 0
y=4-x/2
y=4-8/2
y=4-4
y=0
yes

A. (8,0) works, (6,1) works, (4,2) works
B. (2,4) doesn't work, so this option is wrong
C. (0,8) doesn't work, so this option is wrong
D. (0,8) still , doesn't work, so this option is wrong

answer is A

Where are the
