For this case what you should do is write the table in a software that allows you to graph each ordered pair.
You can use Excel, for example, to graph the ordered pairs in the table.
We observe that when graphing the behavior of the ordered pairs is linear.
The equation of the line is:
y = 2x + 1
Answer:
The rule for the table as an algebraic expression is:
y = 2x + 1
