Finding the first answer is simple. Just plug in the coordinates to the equation.
Ex: y=3x
Take the first coordinates (remember that it is (x,y))
So it would be -9=3(-2)
-9=-6
So the first option is not correct
Just do that with the rest.
The second question is the same idea. Just enter in the coordinates provided.
Comment if you have any more questions. Hope this helps!
