Question

Which rule matches the function shown in the graph?

Points are:
-1, 2
0, 0
2, - 2


A.
y = 2x
B.
y = x + 3
C.
y = x - 3
D.
y = x/ -2

I was doing it checking each one using these rules and so
-1, 2: -2, 2, -4, -0.5
0, 0: 0, 3, - 3, 0

Answer 1

If your point are (-1, 2), (0, 0), and (2, - 2)

then none of the given functions would apply to all the points
