1)
We know that each coordinate (x,y) must therefore multiply to equal 7. The only numbers that multiply to 7 are 7 and 1, so B) is the correct answer.
2)
For this one, just plug in the coordinates they give you for x and y and see if either one works:
So the first one is a solution. Now plug in the second one:
Therefore, the first is a solution and the second isn't making C) the correct answer.
3)
For this one, just plug in the ordered pairs they give you and see which ones end up working:
A) and B) are the only ones that work out, so those are the correct answers.
your domain numbers are (-2,0,3,4)
Hope this helps ;)
