Write an equation to describe the relationship in the table x is 1 y is 2, x is 2 y is 7, x is 3 y is 12, x is 4, y is 17, x is 5 y is 22

Suppose you are analyzing the relationship between time and distance given in a table,and there are 4 values for each quantity.you divide distance 2 minus distance 1 by time 2 minus time 1.you then divide distance 4 minus distance 3 by time 4 minus time 3 and get a different answer.what can you say about the relationship?
