I don’t understand it. Do I need to put the . Together

Recall that the vertical line test is used to see if we have a function or not.
If we can draw a vertical line through more than one point, then it wouldn't be a function. Notice this is the case for the two left-most points (1,1) and (1,3)
If we remove either of those points, then we go from a non-function to a function.
Answer:
no do not put the points together
Step-by-step explanation:
in this equation it surely is not a linear function
so all u have to do is to look for the point which doesn't have a pair,and where the points which have a pair are colliding is your answer which is:(2,2)
