Question

Which two points are on the graph of y = x + 3?

(1, 2), (0, 3)
(1, 4), (-1, 3)
(0, 3), (4, 6)
(-3, 0), (0, 3)

Answer 1

The last pair, (-3,0) and (0,3)

For (-3,0) Y=0 and X=-3, when you plug that into the equation it works:

0=(-3)+3
0=0

For (0,3) Y=3 and X=0, it also works when you put it into the equation
3=(0)+3
3=3

These are the only ones that satisfy the equation.
