I'm doing functions, and I need to write an equation that represents the relationship between X and Y.
(1,4),(2,7),(3,10),(4,13)
I see what it is, but i don't know how to write it in an equation?
it's like adding in the next odd number?
Y = 3X + 1 is the equation
The increase in Y is always 3 times the increase in X. That is called the slope.
