tate the function?
input x . . . . . -3 . . . . . 0 . . . . . 3 . . . . . . 6
output y. . . . . .1 .. . . . . . 0 . . . . . -1 . . . . .. -2
Notice as we move down 1 on the y, -1, then we move up 3, +3, on the x. Our slope is
m = rise / run = -1/3
We have a formula of
(i) Y+=+%28-1%2F3%29x+%2B+b
If x =0, then y = 0. So,
(ii) 0+=+%28-1%2F3%29%2A0+%2B+b
(iii) b+=+0
The function is
y+=+%28-1%2F3%29x
