Will fan and give medal for answer!!! Use the form y=mx +b for linear equations. Write the equation for the following relation. A = {(x, y): (1, 2), (2, 5), (3, 8), . . .}
theres a way to solve such qustions, but i dont know how to explain it through this interface

so the del value becomes constant at the first series of difference, which means that the equation is a 1st degree equation of x with the form f(x)= ax+b. You can find the values of a and b by sustituting the x and corresponding y for 2 instances and solving the equation. It is very simple. I dont know which grade/ class you are so i dont know if you understand this
This is really simple, There is no need to over think it.

@ZakaullahUET gave you the answer. It's really that simple.
