Question

what do we do with the points we plot on a graph
cross them out in order
connect them in order
draw a pretty picture with them

Explanation:

When plotting points on a graph to represent a function or a relationship, we typically connect them in order if they are part of a continuous - like relationship. Crossing them out is not a standard action for representing data or functions. Drawing a pretty picture with them is not the main mathematical purpose.

Answer:

connect them in order
