Really stuck on this one. Which of the following are ordered pairs for the equation y =x - 4?

(0,-4) (-4,0) (-1,-5)

(0,-4) (-4,0) (1,5)

(0,-4) (4,0) (1,5)

(0,-4) (4,0) (-1,-5)

Answer: Choice D

(0,-4) (4,0) and (-1,-5)

===========================================================

Step-by-step explanation:

Plug in x = -4

y = x-4

y = -4-4

y = -8

The point (-4,-8) is on the line instead of (-4,0). This rules out choice A and choice B.

Now plug in x = 1

y = x-4

y = 1-4

y = -3

We get (1,-3) instead of (1,5). So we can rule out choice C.

The answer must be choice D.

The graph is below.
