Question

Which are solutions to y=x-4? Choose all correct answers. (4,0), (3,-1), (6,3), (2,-4)

Answer 1

The correct answers are (4,0) and (3, -1)

Answer 2

Plugin the points and see which ones are true.
(4,0)
y = x - 4
0 = 4 - 4
0 = 0 <---True so it is a solution

(3,-1)
y = x - 4
-1 = 3 - 4 
-1 = -1 <---True so it is a solution

(6,3)
y = x - 4
3 = 6 - 4
3 = 2  <----Not true so  not a solution

(2.-4)
y=x-4
2 = -4 - 4
2 = -8 <----Not ture so not a solution

So (4,0) and (3, -1) are solutions
