The fact family of 0, 0, and 4 would include the addition and subtraction equations: 0 + 0 = 0, 0 + 4 = 4, and the subtraction equation: 4 - 0 = 4.
4
0 (1-1)/4 = 0/4 = 0
16y-9y3 = 0 y*(16-9y2) = 0 y*(4-3y)*(4+3y) = 0 So y = 0 or (4-3y) = 0 or (4+3y) = 0 ie y = 0 or y = 4/3 or y = -4/3
No. The 4 points are (4, 0), (0, 4), (-4, 0) and (0, -4).

I was only able to get 13 but I think there can be more, this is what i got: 0+0+4=4 4+0+0=4 0+4+0=4 0+1+3=4 0+3+1=4 0+2+2=4 1+2+1=4 1+1+2=4 1+3+0=4 2+2+0=4 2+0+2=4 3+1+0=4 3+0+1=4

4-4=0 4 -4 _ 0
4
0
x2 - 3x - 4 = 0 so (x+1)(x-4) = 0, so x+1 = 0 and x-4 = 0, so x = -1 or 4
-4
4
0 is less than 4 but 0 is greater than -4
0 (1-1)/4 = 0/4 = 0
16y-9y3 = 0 y*(16-9y2) = 0 y*(4-3y)*(4+3y) = 0 So y = 0 or (4-3y) = 0 or (4+3y) = 0 ie y = 0 or y = 4/3 or y = -4/3
