Question

I need help im not good at this stuff

Answer 1

I can't see D.

but really all you have to do is plug in the given coordinate into the equations to see which one works

in other words, since we are given (2,1)
we can go through each answer and plug in 2 for x to see if we get 1 as a result

by doing this, we see that only B correlates with this coordinate
